Hello,
is there any way to create a PROM programming file that contains not only Xilinx BIT files but also a Lattice BIT file ?
Best regards, Gerald

yes sure from a company called Xilice :)
NO the answer is NO. if you need several bitstream in one PROM file then you need to write your own tool todo this. hmm you did ask for Parallel PROM and doing download by some micro? or do you want one serial PROM to hold bitsrtreams for multiply vendor FPGAs? if you want to use singel serial config prom for Xilinx and Lattice this maybe a bigger problem, multi chip promfiles are of course possible but how it works if there are fpgas from different vendors I dont know. might be possible, but then its even more problems with bitstreams I would guess.
one thing though Xilinx SYSACE configuration solution is capable to play back SVF files, so it may be possible to have a mixed chain of xilinx and lattice using sysace, unfortunatly the backstage of sysace file generation and SVF usage are not docemented ASFAIK
