Hi Bruce
It seems that the IP you are calling is not found in Xilinx library.
- Can you confirm that during the
make imageflow, 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_decimal_mult action or are you using your own action code? If you could first try with the HLS_decimal_mult 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 image process with the HLS_decimal_mult 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_decimal_mult 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_decimal_mult action with Vivado 2018.1. Let me know how things works.
@bmesnet. I changed the snap version. It worked. I used the latest snap version. And Vivado version is 2017.4. Thank you very much.
Great. Thanks for the feedback. closing the issue so. Have fun
