How to do multiple writes using uvm_hdl_force

[qwerty]

Hi,

 

I my using uvm_hdl_force("path",data) to configure the registers of the design. But the problem is they are large in number so i want to loop them in.

 

for(int i=0; i<8; i++) begin

 for(int j=0; j<8; j++) begin

 

uvm_hdl_force("DUt.abc.pkt.reg_0.w[1]" , data);

 

end

end

 

I want to replace 0 with i and 1 with j . Is their a simple way to do it.

Use $sformatf("DUt.abc.pkt.reg_%0d.w[%0d]", i, j) to return your path string.

used $sformatf to pass it to a string a pass that string to uvm_hdl_force().

thanks for the solution.

You should be able to bypass the temporary string completely and just give $sformatf(...) as an argument to uvm_hdl_force (though I suspect you also wanted to print the string to make sure it works correctly).

hi,

 

if these are bus-accessible registers (not just 'reg' s) then use the register model together with the hdl backdoor instead of directly forcing the values.

Hi Uwe,

 

Any specific reason why not to use the uvm_hdl_force directly?
