Description

We get a lot of warnings like this in the tracer:

Warning-[IDTS] Ignoring dynamic type sensitivity
../src/lowrisc_ibex_ibex_tracer_0.1/rtl/ibex_tracer.sv, 395
"mnemonic"
  Dynamic types used in always_comb, always_latch, always (@*) will be ignored
  for the inferred sensitivity list. 
  
  Declared at: ../src/lowrisc_ibex_ibex_tracer_0.1/rtl/ibex_tracer.sv, 394
  Originating call: ../src/lowrisc_ibex_ibex_tracer_0.1/rtl/ibex_tracer.sv, 
  718

Start by inspecting src/lowrisc_ibex_ibex_tracer_0.1/rtl/ibex_tracer.sv around lines 394-395 and the originating call near line 718. Determine how the tracer's sensitivity warning is produced, then verify that the reported warning no longer appears in the relevant tracer run.
