sysDSP Blocks in the Report File
To check the configuration of the sysDSP Blocks in your design you can look at the MAP and Post PAR report files.
The MAP report file shows the mapped sysDSP components/primitives in your design. The Post PAR report file
shows the number of components in each sysDSP Block. The report files that follow show how the inferred MAC
was used.
