TEMPERATURE SENSOR IP in STRATIX10 SX , READ INCORRECT VALUE

Hi @Wgith,

Sure, keep me posted. Signaltaps would be helpful. Just a note, the SDM can only process 1 IP at a time. So you have to make sure both IPs is back at cmd_ready, and only assert cmd_valid for one of the the IPs (not both together). Hope this helps.

Hi,

Still having issues. I made sure to one enable one of the IP blocks at a time. I also have added very large waits between accesses. I have attached a zip file with my simple vhdl state machine that access the voltage and temperature IPs. I also included 4 signaltap screenshots which shows how I enable the voltage and temperature requests and how it shows the IP responding as expected, and then 2 screenshots which shows for the voltage IP it responds with 4 and not 5 requests and also the 2 requests that actually respond with data that is not zero is formatted in a way that is for temperature readings, not voltage readings. And then for the temperature IP response, I do get two responses, but the second response valid as you can see is 2 clock cycles too late for the second valid data response.

So, the temperature IP is almost working as expected, but the voltage IP is completely responding in a manner that makes no sense.

Note that I am running the IP blocks at 100 Mhz.

Hi @WGith​ ,

Let me take a look at the STP, and I will get back to you.

It would be great if you could share with the me the simple design QAR.

Could I confirm with you that these IPs were working correctly individually?

Hi @WGith​

I took a look at the STP, for voltage sensor, i see you set to read channel 2,3,4,6,9

The results came back for 2,3,4,6...9 is missing. Is that what you meant by "Voltage IP is responding in a manner that makes no sense"? If not, please elaborate.

Btw, what device PN are you using?

Could you share with me the simple design QAR.

@WGith,

There is no errata regarding this.

When you have a simple design, send it over, i can help to check further.

Hi @WGith​

I modified the youtube design example to make it simpler. Upgraded the IP to 18.1, recompiled. Attached file. can you test it?

In System Console, run the below scripts:

# Setting up ISSP

set issp_index 0

set issp [lindex [get_service_paths issp] 0]

set claimed_issp [claim_service issp $issp mylib]

#{cmd_valid, reset, cmd_data [6:0]}

issp_write_source_data $claimed_issp 0x17F

#0x80 TSinactive

#0x17F active

set issp_index 1

set isspVS [lindex [get_service_paths issp] 1]

set claimed_isspVS [claim_service issp $isspVS mylib1]

#{cmd_validVS, reset_VS, cmd_dataVS [15:0]}

issp_write_source_data $claimed_isspVS 0x2025C

#0x10000 VSinactive

#0x2025C VSactive

I haven't had a chance to look at your new example yet. It maybe a while, but here is an archived project of mine. In this design, teh voltage IP appears to work, but the temperature IP is not.
