Re: [microblaze-uclinux] error when 'generating simulation hdl files' in xps

[Sebastian <fatfpga@xxxxxxxxxxxxxx>]

Hi John,

curiously, my BRAM size, the ELF etc. is set right when i synthesize to bitstream completely (no errors)
but i cannot generate the simulation files. I haven't changed anything and used the reference design for spartan3e and 
edk9.1. I am using petalinux 0.30rc1.

I posted my question to comp.arch.fpga and wait for answers.

Thank You

Sebastian
