TCL based assertion for connectivity check

harsharaj

Hi,

 I am using ncsim and i wish to check connectivity between two nets in RTL/netlist using tcl. I remember there being someway where using tcl input file i could specify two nets which could be tested for connectivity.

ex:
 -src net1  -dst net2

on a change of net1 check net2 value is equal to net1 value. kind of an tcl assertion

I dont remember the syntax. kindly help

thnaks!

  •  okay i got the 'puts' working.

     what i need now is to start this check on every change of net1 value. will the below get the job done ?

     

     stop -continue -object tb.inst1.net1 -execute { if {#tb.inst1.net1 != #tb.inst1.net2} {puts "*E ERROR mismatch "}}  

     

    Thanks.
