Convolution function of two temporal signals in Cadence Verilog-A

Hi,

I would like to know how to achieve convolution of two signals in time domain with verilog-a language.

I can totally understand the convolution theory but it is hard to me to realize in verilog-a.

May I know is there any sample convolution function/module? Or any thoughts about the implementation?

Say, we have a standard 10MHz (period 100ms) square pulse train, which is convolved with another single square wave with 50ms duration.

Thanks a lot
