Exclude signal in IMC in command line

Hi,

I met some issue to exclude signal in IMC.

In fact, I'm using the syntaxe given in the help example of IMC HELP as follow:

exclude -inst lib.inst_a(rtl):inst_b:inst_c (WORKING THE INSTANCE IS EXCLUDE)

exclude -inst lib.inst_a(rtl):inst_b:inst_c -toggle rst (NOT WORKING: *W,NOMATCH: No matching entities found for argument 'lib.inst_a(rtl):inst_b:inst_c/rst)

 I have try several write of the command line whitout succes.

 Thank for your help,

BR,

Julien
