RE: [sv-ec] RE: [sv-ac] Seuence Instance passed as an argument to sequence

Hi Surya,

 

Yes, there is indeed an inconsistency in the LRM, I think that instead
of "expression" "sequence expression" should be stated. But the BNF is
correct.

Hi,
As per SV LRM 1800-2005, (section 17.6 Declaring sequences):

An actual argument can replace any of the following:
 Identifier
 Expression
 Event control expression
 Upper delay range or repetition range if the actual argument is $

A sequence instance is not part of normal expression. So as per LRM the
case is illegal.



Regards
Surya

Hi,
 
Is this a valid scenario:
 
sequence s1;
 @(posedge clk) irdy ##1 !trdy ##1 !devsel;
 endsequence
 
 sequence seq (s,trans,grant,n);
 @(posedge clk) s ##1 trans ##1 grant[*n];
 endsequence
 
 property p1;
 @(posedge clk)
 reset |=> seq(s1,next_state==3'b111,stop,4) ##1 frame[*2];
 endproperty
 
 assert property(p1);
 
Most of the standard tools are passing.
 
Thanks,
Sarani
