AR# 8067: FPGA Express: Can not create chip - Unknown error
FPGA Express: Can not create chip - Unknown error
Keywords : Express, Synposys, HDL, Foundation
Urgency : Standard
General Description: When attempting to synthesize a project in Foundation Express, the above error is encountered. When the same project is synthesized in standalone FPGA Express, Express crashes and before any error messages can be read.
This behaviour occurs when FPGA Express encounters an error or coding situation it does not know how to deal with. Examine your HDL code for inconsistencies, especially with hierarchy, parameters, or generics.
Please send testcases that produce these errors to Xilinx (if you are a Foundation or Alliance customer) or Synopsys (Alliance customers only) so these issues may be resolved.
