[Fedora-electronic-lab] thank you for this platform

[Nigel noldsworth]

Hello,

Thank you for this robust platform for digital design. I'm a digital
designer. I was using iverilog and gtkwave on ubuntu. However last
year, I had a lot of issues when doing maths with verilog. Then I
tried Fedora to see if if suffers these issues, but haven't
encountered any. I was impressed and sticked with Fedora ever since.
With the recent gplcver and vrq, it makes verilog design exciting.

In the meantime, I'm learning vhdl on my own and am unable to get the
name of the current state of the state machine on gtkwave. Is there a
solution for that so that I don't have to declare a special
non-synthesized std_logic_vector.

Hello Nigel,

Thank you for your feedback. We appreciate it.

There was recently a thread in the iverilog mailing list about this
maths issue with Ubuntu's iverilog. This issue is still present on
Ubuntu with the next iverilog release. The test we have conducted
against iverilog on Fedora does not reflect this maths issue.

As Shakthi pointed out, extract the waveforms with --wave=design.ghw
instead of VCD.
