How can I create a PROM file for a Platform Flash PROM used to configure a mature FPGA (Spartan/-XL, XC4000)?
When using iMPACT/PROMGen 7.1.04i to create this PROM file, the iMPACT GUI crashes after showing the following error message:
Only ISE Classics edition (http://www.xilinx.com/ise/logic_design_prod/classics.htm) fully supports mature FPGAs.
These FPGA families are not supported in ISE 7.1.04i.
Because of this, PROMGen 7.1.04i cannot identify the FPGA and gives an error message when generating a PROM file used to configure mature devices.
However, Platform Flash PROMs are not supported in ISE Classics.
To work around this issue, use iMPACT/PROMGen 6.3.03i which will enable you to create a PROM file that can be stored in a Xilinx Platform Flash to configure a Mature FPGA.
This problem is solved in ISE 8.1i.
