Facing issue while generating verilog about chisel-tutorial

[ucbjrl]

I've verified that this is an issue with newer versions of verilator. Until we update chisel3 to work with recent verilator releases, I suggest you use: Verilator 3.904 2017-05-30

@Sairam-Ganti this looks like a chisel3 version issue. Is it possible you have an old version of the chisel-tutorial repository? Please type the following command in the chisel-tutorial directory:

$ git log -1

This should give the last commit for this clone of the chisel-tutorial branch. A:

$ git checkout release
$ git pull

should get you the latest version, after which an:

$ sbt clean "test:run-main examples.Launcher GCD --backend-name verilator"

should work. If this still fails, could you issue the following command:

$ sbt clean "test:run-main examples.Launcher GCD --backend-name verilator" >& sbttest.out

and attach the generated sbttest.out file.

@ucbjrl
git log -1 gave me the following output (Note: I'm already at the latest version)

`commit 1f8d68e
Author: Jim Lawson [email protected]
Date: Wed Nov 29 13:10:51 2017 -0800

Bump release versions (#109)

* InvalidateAPI - Initialize all router outputs.

* Add "last connect" semantics comment.

* Fix comment in Adder (problem and solution).

* Enable cross-compile. (#108)

`
And, it failed again, attaching the sbttest.out file here.

Thanks @Sairam-Ganti. This looks like a chisel3/verilator version mismatch. Which version of verilator are you using?

[Sairam-Ganti]

@ucbjrl Thanks, will switch to the specified version and update with the result

Hi, so I switched to the specified version of verilator and now I get the following error:

It seems like it cant find the "3.1-SNAPSHOT" from chisel-iotesters.

Based on the unresolved dependencies, it looks like you've trying to use the master branch version of the tutorials. You should be using the release (the default) branch, which uses the published versions of the chisel dependencies.

% cd <...>/chisel-tutorial
% git checkout release
% git pull
% sbt test

You may use the master branch, but if you do so, you need to clone the chisel dependencies (firrtl, firrtl-interpreter, chisel3, and chisel-testers), and publishLocal each of them in that order.
The master branch is targeted towards those developers actively developing chisel tutorial code. The release branch is for those using the chisel tutorial to learn about chisel.
