Aurora 8B10B for Virtex-4 FX FPGA Generation Failed Using ISE 14.7

Started by Multan007 4 years ago2 replieslatest reply 4 years ago74 views

I am trying to generate the Aurora 8B10B core for Virtex-4 FPGA using ISE 14.7 in Windows 7  (64 bit) OS based on the procedure presented in LogiCore IP guide. But, after running 18% of core generation, I see:

WARNING:coreutil - WARNING: EJava Unzip Failure on for ./\\aurora_interface\ Zip/Jar file, C:\Xilinx\13.1\ISE_DS\ISE\coregen\ip\xilinx\network\com\xilinx\ip\v4fx_aurora_8b10b_v3_1\, is not a valid file.

WARNING:sim:93 - NGC output will not be generated for this core.

Finished Generation.

ERROR:sim - c_mgt_clock_1: Invalid value 'None'.

ERROR:sim - Failed to generate ASY schematic symbol.

Could you please advice the cause and possible solution for this warning and error?

I appreciate your suggestions. Thanks for your answer and time

I was told by a Avnet support engineer that ISE 14.7 works best on Windows 7 32 bit. I had similar issues with later versions of ISE 14.7 and switched to WIndows7 32 bit, works fine, I got a 10 year old laptop  repaired for this. It was worth it.

Thanks for your kind response. But, unfortunately we do not have 32 bit right now. However, I will try manage 32 bit and run the test again. Hope, you suggestion will work!
