< code > I'm sharing this code which shows how to connect a verification component,a monitor in this case, to an existing hierarchy, without modifying ANY of the DUT code. The attachment of the verification component to the existing dut using an interface is a bit confusing, but is explained here. The value of this technique is that a verification engineer can instrument a dut without touching any of the original source code.You can put all the below code in a file called top.sv and use the following to compile:irun top.sv -linedebug -gui
// This is the interface for the verification component// Since the verification component is a monitor function// all signals are input to the verification componentinterface verif_if(input a, b, c, d);
// -------------------// This is the hierarchy that the v_monitor will be attached tomodule dut(input logic mclk, input logic msig, output logic msigo);
logic aa='b0; // other potential signals for V1 to attach to
always #17 aa = ~aa;
always @(posedge mclk) $display("%m mclk being clocked");
always @(posedge aa) $display("%m aa being clocked");
assign msigo = ~msig;
// ------------------module top();logic tclk='b1;logic tsig='b0;
dut U1(.mclk(tclk), .msig(tsig), .msigo(tsigo) ); // .lower(upper)
always #10 tclk = ~tclk;always #13 tsig = ~tsig;
//always @(posedge tclk)// $display("%m tclk being clocked");
// ------------------// The verification module is a seperate top module whose sole// purpose is to bind verification modules (v_monitor) into // an existing design (dut) without modifying anything in the// existing design.
module top_verif( );
// when using an interface to bind signals into the verification// component, bind the interface first, then the verif component// can connect ports and internal signals:
// bind an interface of verif_if called myif to // instance top.U1 using the following port listbind top.U1 verif_if myif(mclk, msig, msigo, aa);
// Create an instance called V1 of v_monitor and attach// it to the instance at top.U1 using the interfacebind top.U1 v_monitor V1( .vif(myif) ); // .lower(upper)
//----------------// This module gets attached (uses SV 'bind') to dutmodule v_monitor(verif_if vif); // monitor = all inputs// In a real monitor insert covergroups, assertions etc here
always @(posedge vif.a) $display("V1 a being clocked");
always @(posedge vif.d) $display("V1 d being clocked");
