ncsim: *E,TRSRANGE: range constraint violation (signal update).

zoombarabar

Hello,

I am able to run the simulation without any problems on modelsim. The same testbench on ncsim gives me the error after the simulation starts and runs for about 5us.

Can someone please help me with this? My assumption is that it points to the following two lines of code:

psi5_s <= (ano => ANALOG_Z, ani => psi5_i_s); 

psi5_o_s <= psi5_s.ano;

Any help will be great. 

Best regards, 

Vidya.

  • Vidya,

    I think we'll need to see the declarations for the signals and their data types.
     Also, remember that the value assigned to psi5_o_s will not be the new value assigned to psi5_s, but because of VHDL delta cycles, it will be the old value of psi5_s.ano before it was updated.
