FSM transactions are not extraced in ICCR tool(vmanager)

buddi

hi

i am unable to view FSM transactions in ICCR tool.

and observed the follwoing error in my log

ncelab: *W,COVFHT: FSM hold transitions (transitions to the current state) are not extracted for any FSM in default mode.

 

Enabling instrumentation for coverage types: block expression FSM toggle functional

what is the command need to extract FSM transactions should be used in irun

2) 

how i can remove this warning

ncelab: *W,COVDCL: By default coverage is scored only for Verilog logical operators (|| and &&) and VHDL logical operators (OR, AND, NOR, and NAND), and is scored only in condition expressions. To score coverage for other operators, and for expressions in assignment statements, use the "set_expr_scoring -all" coverage configuration command at elaboration

  • The ‘nchelp ncelab COVFHT’ command returns the following information:

    ncelab/covfht =

            To extract FSM hold transitions, specify the "set_fsm_scoring

            -hold_transition" command in the coverage configuration file, and then

            pass it to ncelab using the "-COVFILE" command-line option. Scoring

            hold transitions might have a performance impact.
