An example of how wires should be constructed in the database would be very helpful - its not intuitive from just looking at the names of the functions that are available.

Recently, a spdlog library was added:

Please let me know if you need more information.

Now that OpenDB can read a 5.8 LEF file, how can I access the information that has been read using the TCL API?

The lefout.h was recently modified and now fails to compile on our systems. It would appear the issue is a missing #include <string> in at the header of the file

Please let me know if you need more information.

Thanks,
Peter

I can create a net using dbCreateNet e.g.
set net [dbCreateNet $block "VDD"]

Normally I use $net getSWires to examine the set of wire segments for this net, but how do I add a wire segment to the net?

Hi I'm tring to read the spacing table of a layer in LEF. The table is a 2d table with indices of width and length.

I can use the getV55SpacingTable() to read the entries of the table. But how do I read the index array of width and length?

I can only use the getMaxWideDRCRange() and getMinWideDRCRange() to get the max and min of width and length, but how about the values in the middle?

I've needed to comment out this test addition because it uses an issue on non-standard installs with TCL. But since this is a test, shouldn't this directory only be included when compiling for debugging?

Thanks,
Peter

There are some use cases where it is necessary to be able to delete objects from the database. For example, the PDN module inserts a power grid for the design, but this will clash with any existing nets defined in the incoming database.

There is a -delete function on many of the objects, however, this seems to delete the TCL object and doesnt affect the underlying database.

I am not blocked by this issue, as I can massage my incoming testcases - removing offending objects in my input DEF before loading into a database, so I would consider it "low" priority.

I have "Red Hat Enterprise Linux Server release 6.9" - in order to make the build process work I need to add the line

add_link_options(-lrt)

into the CMakeLists.txt file. Tested this out on UCSD machines, and the build is still successful with that setting. Please can this option be added into the CMakeLists.txt file.

The integration of OpenDB with Python provides it as a package that gets loaded into the Python interpreter.

The same can be done with TCL. Rather than having a separate executable, if opendbtcl is built as a shared object library, then it can be loaded into any TCL shell through the package loading mechanism.

Alongside the shared object library there would be a TCL file called pkgIndex.tcl, which would load the shared object library if required. This would look something like:

package ifneeded opendbtcl 1.0.0 [list load $dir/libopendbtcl.so]

The end user would add the path of the directory where the pkgIndex.tcl file could be found to the environment variable TCLLIBPATH so that all the packages are known (but not loaded) when the tclsh starts up.

More information on the TCL load command:
http://tmml.sourceforge.net/doc/tcl/load.html

To use the opendbtcl package, the end user would do the following:

% tclsh
> package require opendbtcl

Taking this approach will make the python/tcl approach more consistent and tidy up some loose ends in the current opendbtcl binary [e.g. the package mechanism not working]

The command to create a row seems to be of the form:

dbRow_create block name site origin_x origin_y orient direction num_sites spacing

e.g.
dbRow_create $block abc $site 0 0 N horizontal 400 480
TypeError in method 'dbRow_create', argument 6 of type 'dbOrientType'

How do I create a dbOrientType to use for this - shouldn't the wrapper convert a string argument for me?

Running the enclose tcl script on a DEF with a component that has a HALO defined, the output DEF has written an illegal syntax for the HALO description. From the transcript you can see that parentheses have been used
halo_test.tar.gz
when writing out the DEF that should not be present.

It is not normal practice to concatenate LEF files together into a single file before reading into a tool.

Normally there is a single LEF file that defines the technology - this file is specified first in a list of LEF files, and is read first in order to define all the layers etc. Subsequent LEF files are read and add cells to the library.

Need to have a function available from TCL to load a DEF file that will append it's data into an existing design.

Currently apply_pdn works by generating a DEF file, then merging it with the original input DEF file. This capability is available in existing EDA tools.

The README.md file in the project does not have the instructions to install the dependencies flex, bison, tcl-dev to build the project. I would like to add it to the README.md file.

The enclosed testcase.tgz includes data and unit tests to be added to OpenDB.

The library data is based on the nangate45 open library

The first testcase, gcd_def_access_checks.tcl looks at floorplan.def. 43 out of 54 tests pass in this suite.

The second testcase, gcd_pdn_def_access_checks.tcl looks at gcd_pdn.def. 50 out of 69 tests pass in this suite

The TCL function dbVia_setViaParams doesn't accept enough arguments, so I'm unable to set the via parameters

% $block getVias
_a0b0839e267f0000_p_odb__dbVia
% set via _a0b0839e267f0000_p_odb__dbVia
_a0b0839e267f0000_p_odb__dbVia
% $via hasParams
0
% set params [$via getViaParams]
_b048730100000000_p_odb__dbViaParams
% $params setNumCutRows 3
% $params getNumCutRows
3
% [$via getViaParams] getNumCutRows
1
% $via hasParams
0
% $via setViaParams $params
Wrong # args.:dbVia_setViaParams self argument 2

Clearly [$via getViaParams] is returning a copy of the viaParams object. This being the case, I need to be able to set the params to a modified set by calling the $via setViaParams function - however, this function does not accept a dbViaParams object as an argument.

The code:

set db [dbDatabase_create]
dbChip_create $db

does not create a chip object, returning NULL instead.
A chip object needs to be passed to dbBlock_create to allow a block object to be created

At the end of a session with the database I should be able to save the current database to a file, then I should be able to exit the tool, restart and load the database so that I'm back at the same position.

Currently all the examples are of the dbDatabase_create variety.

If I try to save a database with dbDatabase_write I get a type error

% $db write test.odb
TypeError in method 'dbDatabase_write', argument 2 of type 'FILE *'

For read:
% $db read test.odb
TypeError in method 'dbDatabase_read', argument 2 of type 'FILE *'

does this imply that I have to create a database in order to load a database?

Adding the following code to the TCL routine that is executed at startup will enable the package loading mechanism to be enabled.

foreach dir $env(TCLLIBPATH) {
    if {[file exists $dir/pkgIndex.tcl]} {
        source $dir/pkgIndex.tcl
    }
}

Note the loop variable dir is used inside the pkgIndex.tcl files to load the TCL source code for a package when the package require command is called.

There are some properties stored in the DEF that I need to get access to from the TCL interface, but it's unclear how I would go about accessing them.

% dbProperty_getProperties
Wrong number of arguments :dbProperty_getProperties object argument 1
% dbProperty_getProperties $block
TypeError in method 'dbProperty_getProperties', argument 1 of type 'dbObject *'
% dbProperty_getProperties $db
TypeError in method 'dbProperty_getProperties', argument 1 of type 'dbObject *'

Is there some additional SWIG support required for properties?

The project currently degined in the CMakeLists.txt includes a "DESCRIPTION" parameter. (https://github.com/The-OpenROAD-Project/OpenDB/blob/master/CMakeLists.txt#L14)

The DESCRIPTION parameters was added in CMake 3.8, and so this is breaks compilation on platforms with CMake <= 3.8

Either remove this parameter or bump minimum cmake version required to 3.8

The specific error using cmake 3.3.2 is as follows

Hi all,

I tried making an application. My Makefile is:

A sample of such statements can be seen in the .defok files in most of the tools. For example:

Thanks.

I wrote some additional tests to examin vias that are created from via rules - the tests pass, so nothing to fix, but it would be good to incorporate the tests into the regression test suite.

On CentOS 6 the default version of swig is 1.3.40 but OpenDB fails to build. I was able to get it working by updating to a new version of swig (I used 2.0.8).

Please bump the minimum version of swig required in the CMakeLists.txt

I observe the following error using SWIG Version 1.3.40

[ 98%] Building CXX object src/swig/tcl/CMakeFiles/opendbtcl.dir/opendb_wrap.cpp.o

Is there a reason that the following lines require a dbSBox to have an even dimension (in DB units)?

The test creates some rows with various settings for direction and orientation. Examining the row settings immediately aferwards shows that the values are incorrect.

If I try to set the version of DEF to be writteon out, I get:

ERROR: set defout version: Command {$def_writer setVersion DEF_5_6}
TypeError in method 'defout_setVersion', argument 2 of type 'odb::defout::Version'

I've updated one of the tests to include this check
07-write_def_test.tcl.gz

The header of the def is:

% more ./OpenDB/build/test.def
VERSION 5.3 ;
NAMESCASESENSITIVE ON ;
DIVIDERCHAR "/" ;
BUSBITCHARS "[]" ;
DESIGN counter ;
UNITS DISTANCE MICRONS 1000 ;

the VERSION value is hardcoded in the defout code. (The version in the incoming DEF is 5.7, so unless otherwise modified by the user, this should be the default value used for the def out version as well)

You seem to be missing that....

Hi I'm a student from UT Austin and I'm trying to use OpenDB to read Lef/Def for my router which is in C++.
My understanding of using it is:
dbDatabase db;
lefin lef(&db, false);
defin def(&db);
lef.readLef(lefFileName);
def.createChip(.....);
etc.
My question is, the readLef function in lefin is private. I'm unable to call it. Should it be public?
Could you please provide a simple example just to show how to read and write LEF/DEF?

I've found out that the following nangate45 cases show this problem:
filler_source_test.tar.gz

commit: 5fc66c3

I only used odb_read_lef, odb_read_def and odb_write_def, but the generated DEF doesn't have "+ SOURCE DIST" statements.
This caused a failure to OpenDP JenkinsCI testcases on the integrated top-level repo.

Could you check this problem?

https://github.com/The-OpenROAD-Project/OpenDB/blob/master/src/swig/tcl/CMakeLists.txt#L20

Please use the library returned by FindTCL.cmake

According to the header comments in db.h#L934:

    /// Get the parent block this block. Returns NULL if this block is the
    /// top-block of the chip.
    ///
    dbBlock * getParent();

However, when getting the parent of a top-level block in the tcl shell, it causes an assertion failure and crashes the shell:

opendbtcl: /OpenDB/src/db/dbTable.h:126: T* odb::dbTable<T>::getPtr(uint) const [with T = odb::_dbBlock; uint = unsigned int]: Assertion `(id != 0) && (page < _page_cnt)' failed.
Aborted (core dumped)

I would expect the function to return NULL or gracefully error. Is this the expected behavior?

A code snippet which will reproduce the crash:

set db [dbDatabase_create]
set lef_parser [new_lefin $db true]
set def_parser [new_defin $db]
set lib [lefin_createTechAndLib $lef_parser gscl45nm ./OpenDB/tests/data/gscl45nm.lef]
set chip [$def_parser createChip {$lib} ./OpenDB/tests/data/design.def]
set block [dbChip_getBlock $chip]
dbBlock_getParent $block
