1. Find all rects connected to a net, probably just need to iterate over instance ports and figure out who's connected where. Maybe make the graph when the ports are made?
2. Use the sort option to figure out who should be on top, but how do I figure out where it starts? and what is the stop rectangle?

Should implement load of Route, Guard, Routering etc from Json

This is a natural state of QWidget, but it should be fixed at some point

Required for placement of ports

For example, if multiple ports on an instance are connected to the same net it won't necessarily add them all.

Connectivity route is supposed to match with regular expressions the graphs that should be routed, however, it now makes a mistake.

• Wrong: "C(P|N)I" will create one route that includes all rectangles
• Correct: "C(P|N)I" should find CPI and CNI graphs and route two routes.

Intro

Currently ciccreator outputs a SPICE that can be used for LVS, however, there is always some mismatch between what is in the CDL (names of devices, types of devices), and what is needed to do netlist import. Should really try to make an intermediate output:

Layout output

Currently cic outputs .json files that contain the json dump of the Design object. This is used by cic-gui to load the generated output. Should rename this to .cicl (cic layout output)

Schematic output

Currently cic outputs .spi file and tries to use the device map in the technology map to adapt the spice. However, the CDL, SPICE import and spectre netlist probably need slightly different device definitions, thus I should make an intermediate format that easily can be parsed by a script (in my case Perl) to generate the different variants of SPICE.

So cuts have no instance name in the cic file. I wonder if they should have that. I can't remember why I choose to leave the instance name empty

Searching for paths deep in the hierarchy works fine, but top level connections does not work, should search instances for ports matching description. Problem can be seen on IVTRIX1_CV where it can't find CN and C ports.

Need to fix the aicex docker

Probably need to change calcBoundaryRect in layoutcell to ignore "Route" objects

Currently cic-gui is using QWidget for drawing etc, however, it seems like QGraphicsView is a much better class for this.

Hi Carsten,

As I was playing around with ciccreator and running some tests, I kept getting segmentation faults when using the examples/routes.json.

The code crashes at the TEST_R and TEST_MY cells due to the LayoutRotateCell property. When I remove the field "class" : "Layout::LayoutRotateCell" it works all the way to the end, but there is no rotation to the resulting layout despite the "rotateAngle" : "R90" property.

I've tested with the master branch version and release 0.1.5 with same results. I'm compiling the software by running make on a Debian machine

Also, in the examples I have not seen any vias being generated, even on the SAR example. Is there a particular version of the tool for which the examples where created?

Thank you!
