How do I restrict the "step" to my TB & source codes in Questasim?

Hi there,

I recently came across this function to show the execution of codes in Questasim. It's useful for small simulations for someone used to programming.

However with UVM testbenches, I see the UVM library codes most of the time. How do I change that function to limit print to my RTL and TB codes only? What is the reference I use to write such scripts?

proc linetrace1000 {} { for { set n 0} { $n < 1000 } {incr n} { step; see 0 }}

    You may try the following. "rtl" represent the path of your RTL file and "tb" for the path of your testbench:


    proc linetrace1000 {} {

    for {set n 0} {$n < 1000} {incr n} {

    step

    if {[file tail [pwd]] eq "rtl" || [file tail [pwd]] eq "tb"} {

    puts "[pwd]: step $n"

    }

    }

    }
