Regarding Smoothness in transient analysis

RFStuff

 Dear All,

I created a verilogA module.

What it basically does is as below:-

It is a simple sine wave generator. 

I stored the sine wave  time & amplitude in a text file for one period of the sine wave.

The verilog A code reads the file and generates the sine wave for the entire transient simulation time.

But the problem is:-

If I am not using the strobeperiod, the curve is NOT smooth at all.

But when I use stobeperiod=1ps then it becomes smooth.

I was thinking that the  transient simulation will be evaluated at each time point stored in the file.

Can anybody please tell why this is happening.

Kind Regards,

Parents

  •  Thanks a lot Lawrence & Andrew.

    I have never come across the bound_step() function. 

    What it is actually ? Is it a OCEAN function . I searched in OCEAN document but couldn't find this one.

    Can you please explain how it actually work or point me to the doc or link where I can know about this function.
