RE: [sv-bc] Query related with clocking block declared inside program block.

Dhiraj,

 

Those restrictions have been changed - please check the latest LRM
(Section 23), which includes significant changes to that section.

 

At any rate, even according to P1800-2005, there is no such thing as an
assignment to a clocking-block variable, the only operator defined on
such objects is the synchronous drive that uses the <= syntax. So your
example is incorrect. There also no signal named outp in the scope of
the program so there's at least another error.

 

            Arturo

program block.

 

Hi,

I have a query related with the clocking block declaration in program
block.
Please see the example below.

module top(input in1 );
program pblk1 (input sclk);
    clocking c_s @(posedge sclk);
        output #1ns outp ;
    endclocking
    initial 
        c_s.outp = #1ns in1 + 2;  //should it be  allowed?? 
endprogram
pblk1 I1 (in1);
endmodule

Now to drive the clocking block output, we have to use synchronous
drive(<=/non-blocking) but
according to LRM,P1800-2005,section 16.2,program block variable should
be assign through 
blocking assignment so what should be the status of above testcase??
should it be positive??

Thanks,
Dhiraj
