Could not find pin on cell 'XADC'

Jump to solution

Hi,

I am using FPGA XC7z045. 

I am trying to connect a XADC to PL for reading on-chip temperature. I generated XADC IP (AXI stream based), and connected in my design. It successfully compiled and simulated well.

But I had the following errors during the synthesis:

INFO:  [Synth 8-113] binding component instance 'inst_xadc' to cell 'XADC'  
ERROR: [Synth 8-212] could not find pin 'm_axis_tvalid' on cell 'XADC'      
ERROR: [Synth 8-212] could not find pin 'm_axis_tready' on cell 'XADC'

ERROR: [Synth 8-212] could not find pin 'user_temp_alarm_out' on cell 'XADC'
ERROR: [Synth 8-212] could not find pin 'ot_out' on cell 'XADC'

ERROR: [Synth 8-212] could not find pin 'alarm_out' on cell 'XADC'          
ERROR: [Synth 8-212] could not find pin 'eos_out' on cell 'XADC'            
ERROR: [Synth 8-212] could not find pin 'busy_out' on cell 'XADC'           
ERROR: [Synth 8-285] failed synthesizing module 'misc'     

All the inputs/outputs of XADC cell could not be found. For Vp_in and Vn_in, they are propagated to the top level in my design, and in the top level xdc file, they are constrained. For the rest signals, they are all used internal. I didn't make any specific contrains for them. I don't think that is the issue.

It seems like I am missing some constrains for XADC cell itself. Is that the case? But in the generated files, I found nothing related to this issue.

I didn't find any info on the Internet. Does anybody have an idea?

Thank you very much,

My instance name is called xadc. Appreantly, it is not allowed. After changing the name, the issue is solved.
