vhdl-sem.adb: fix incorrect che… testsuite/gna: add a test for c… (compare)
Hey there !
I have a design which produce a lot of
../../src/ieee/v93/numeric_std-body.vhdl:1336:7:@0ms:(assertion warning): NUMERIC_STD."<=": metavalue detected, returning FALSE
While I know what produces it (uninitialized values), I would like to know which function produced it.
I wanted to trigger this warning as an error using
--warn-error and check the backtrace, but it seems that this option does'nt exists for simulation time (
-r command). Could you confirm this ?
As I run ghdl through cocotb, I don't have control over the actual command, I can only add parameters.
/opt/ghdl/bin/ghdl -r --workdir=sim_build -Psim_build --work=work ENTITY --vpi=/home/jfaucher/.local/lib/python3.8/site-packages/cocotb/libs/libcocotbvpi_ghdl.so --warn-error
SIM_ARGSsomewhere in your own Makefile: https://github.com/cocotb/cocotb/blob/master/cocotb/share/makefiles/simulators/Makefile.ghdl#L79
Makefile.ghdlinto your project.
COMPILE_ARGSwould be another candidate to try.
cocotb-config --lib-name-path vpi ghdl. And you will also need to set the
MODULEenvironment variable at a minimum to find tests. See my crappy basic Makefile I threw together because I didn't feel like figuring out which of the 3
*_ARGSvariables did the thing I needed it to.
Yes, but my point is that the warning I want to backtrace is at simulation time
I think that using the warn arguments for analysis and elaboration is not limited to those stages. You are telling GHDL that you want those features enabled.

Let's see if we can have a LinkedIn survey with any statistical significance https://www.linkedin.com/posts/plc2-gmbh_vhdl-osvvm-fpga-ugcPost-6817744189200076800-OUeX
Open Source VHDL Design Explorer (OSVDE) is a PoC for showcasing the capabilities of the abstract language model provided by pyVHDLModel and pyGHDL. It's a tkinter GUI for exploring VHDL repos/projects.
Kudos to @Paebbels and Tristan Gingold! :heart_eyes:
