Is there an existing CVA6 bug for this?

  • I have searched the existing bug issues

Bug Description

in uvml_mem_vp.sv, function post_write uses the debug task. This raises an error during elaboration with xcelium :
xmelab: *E,BADBTF (cva6/verif/env/uvme/uvml_mem_vp.sv,98|8): Function "post_write" cannot enable a blocking or a virtual task "debug"

As function are not allowed to consume simulation time this is a problem : the debug call should be removed or updated to a function that does not consume simulation time. Alternatively the post_write function and all its parents / caller should be changed to tasks.
