How to connect the blocks between the core of Sopc and my circuit

Maybe you can use PIO. You have to include PIO´s in SOPC Builder and then you can use them outside your CPU.

Sorry, i think i know what you say.

But, I think maybe problem not clearly.

I already used the PIO, but it's not working.

when I load my circuit into the FPGA.

i didn't see the result that I want.

It also depends from what type of interface your pwm circuit has.

If it has a plain n-bit input port which directly set the pwm duty cycle, then it should work connected to pio.

If it has a specific bus interface (addr,data,wr,rd,ce,...) then your sopc must provide the same interface in order to set the required registers

then post more about your project to get help, Using PIOs are the fastest way to get your PWM to interface with SOPC

thanks for your suggest.

I use the method that you said. It's workable.
