Beginning with 4.1i PROMGen, MCS files have 32-bit addressing. Will this cause problems with other tools?
Pre-4.1i Xilinx download tools (including Hardware Debugger and JAG Programmer) will have a problem with 32-bit addressed MCS files. Version 5.02 of the HW-130 software is the first version to support 32-bit addressed MCS files; however, the 32-bit MCS standard has been in existence since 1988, and all third-party programmers should support this format.
If you must have a 16-bit addressed MCS file, you can set the environment variable XIL_PROM_MCS16 to "Yes".
