What are the limitations that should be considered for the total number for coefficients (the number of coefficient set * number of coefficients per set)?
Why do I encounter the following errors when trying to generate the core with a large number of coffins:
"ERROR:coreutil - Failure to generate output products ERROR:coreutil:424 - An error occurred while running Java. Please examine the console or coregen log file for a specific IP related error. For more information please search the Xilinx Answers Database for this error:http://www.xilinx.com/support"
This is a known limitation of the FIR Compiler.
This is known to occur when trying to build a filter with more than 34 coffin sets with 1024 coefficients in each set.
Below are 2 of many possible ways that can be used to work around this limitation:
1. Break the filter up in to several smaller filters. 2. Use a re-loadable filter, and load the coefficients from memory.
