[troore]

The code in this repo contains very basic verilog/systemverilog syntax errors. I wonder whether the contributors have used some fancy syntax auto-fixing tools.

[adam-maj]

@troore Might just be using a newer version of SV than what you're system is using

[xiyunanhai1995]

@adam-maj I encountered the same problem. My system information is as follows: MacBook Air M1 2020, MacOs 12.7.1 python: 3.10.2 Icarus Verilog: 11.0 (stable) cocotb: 1.8.1 sv2v: v0.0.11-0-g6082cae GNU make: 3.81 Which software of mine needs to be updated? could you list your software version. Do XCode also need to be installed? Looking forward to your reply very much, thank you.

[peilin-chen]

I also meet the same errors as JunChi1022. But I have solved this problem. The reason for this problem is that some systemverilog files in src folder have syntax errors. After correcting these errors in the files, I run the simulation successfully.

[adviyer]

Do you have the -g2012 flag in your Makefile? That should fix these issues by using a later version of SV instead of the default 2005

Yes, I have already pull the latest patch. I think i have met the problem same as: https://github.com/adam-maj/tiny-gpu/pull/13

Did you modify the input reg to input wire?

@adviyer I don't think -g2012 can fix this issue. It is a basic verilog issue as the input of iverilog in the Makefile is .v rather than .sv. I don't remember in any history version of verilog, reg is allowed for input.

Besides, there are other errors which may cause other simulation tool fails (iverilog may succeed).

[adam-maj]

Will look into this one. Probably my use of SV/2012 syntax is breaking things in many places for people using older versions of any software.

Curious why it's working for some and not for others - my guess is people are using different downloads for iverilog/other tools - if so will update readme with proper links.

I downloaded sv2v (version v0.0.12) again from https://github.com/zachjs/sv2v/releases, it be updated 2 weeks ago. the issue can be fixed. Thank you for sharing this project!
