Hello,

I want to build a CCO model that can take external reset signal and using idtmod() function to integrate.

The code I got looks like this:

analog begin
     
     ip = -(I(IBOT_P));

     if ((V(RESET)-vth>0)) begin
           freq_p = 0;
     end
     else begin
           freq_p = KICO*(ip)+ Fc;
     end

     phase_p = idtmod(2*`M_PI*freq_p,0,`M_PI,0,1p);

     $bound_step(1.0/(step*Fc));
     
     V(PH_P) <+phase_p ;
     
end

The problem is when reset is active it just hold current value, and later starts again from that previous position. I want the integrator to start from 0 again after reset is low.

Any comment is appreciated.

Thanks
