FPGA Connection to Processor eSPI Interface

[Annu]

How do we connect the processor with eSPI interface to Cyclone 10 LP FPGA. And what are preset settings to be made in Processor and FPGA for establishing the connection. The IP, Intel eSPI slave  slave does it use any dedicated pins for establishing the connection?

Hi Annu

For the connection between the processor with the Cyclone10, you could use the eSPI Slave soft IP.

7. Intel eSPI Agent Core

It is available for the Cylone10.

Is there any example designs available for the eSPI slave IP? 

[JingyangTeh]

Hi

Sorry we do not have an example designe for eSPI at the moment.

If you could share the testbenches and waveforms for the Intel FPGA slave it would be helpfull

Hi 

We are utilizing the cyclone 10 LP FPGA and SMARC module conga SA7 to communicate the register mapping via ESPI logic. So could you please share the testbenches and waveforms for the ESPI Slave IP

So could you please share the testbenches and waveforms for the ESPI Slave IP.It would be very helpful for me if you could provide a testbench for read and write access from / to a peripheral channel.

HI Annu

You could take a look at the files below for the simulation using vsim.

Hi Annu

Any follow up question on this case?

Your Logs show the virtual wire usage. I wanted to use the commands PUT_IORD_SHORT and PUT_IOWR_SHORT. I have tried configuring the channel zero and tried the same. I was not able to see the output in response while using PUT_IORD_SHORT. Please suggest any resolution
