Hi Bruce It seems that the IP you are calling is not found in Xilinx library.

Can you confirm that during the make image flow, you have the 3 lines I have highlighted below with >> <<?
Are you using the latest master branch of the snap git?
Which Vivado release are you working with?
Are you trying to build an image with make imageusing the _HLS_decimalmult action or are you using your own action code? If you could first try with the _HLS_decimalmult action, this would validate the entire process first.

(extract of the make image flow)

FYI as a test to confirm the entire flow on this specific point, I have just reran successfully the entire make imageprocess with the _HLS_decimalmult action and with the latest snap release using Vivado 2018.2.

Thank you very much. @bmesnet. I use capi 1.0. So the snap is not the latest version. And my Vivado version is 2017.4. I didn't use the _HLS_decimalmult action but my own action code. I will update the software and try again. Thanks for your suggestions again.

Thanks @myheartisweeping for the answer. I have checked that our CAPI1.0 jenkins tests worked ok on this _HLS_decimalmult action with Vivado 2018.1. Let me know how things works.

myheartisweeping commented 5 years ago

@bmesnet. I changed the snap version. It worked. I used the latest snap version. And Vivado version is 2017.4. Thank you very much.
