Returning error from Modelsim to bash script

[braam7]

I'm having trouble returning an error code from VSIM.

Modelsim is running a SystemVerilog testbench which either $finishes (PASS) or gets an $error (FAIL). I'd like to be able to interpret the error from VSIM in my bash script.

Currently the run.do file looks like this:

onerror {quit -code 400}
run -all

and is run with

 vsim tb -novopt -do run.do -quiet -c

If I run

 echo $?

after the vsim command and just get a 0 back.


Any ideas what I'm doing wrong?
