Hi everyone, (this is my 1rst post here)
I'm trying to use the UFM macro on a MAX 10 - 04. I've generated a customized IP (see parameters below, as set by QSys ip generator). I've also generated a .dat file (see below) with 18432 32-bits values, for UFM initialization. In my simulation test bench I read some addresses of it. It does work for lower addresses (up to 0x4000), but for higher addresses (as soon as i try to read 0x5000) I get wrong values, like 0xFFFFFFFF (see attached waveform!)... as if the memory hasn't been initialized with the .dat values. This seems to match with the start of "sector 2" as defined in the module parameters by qsys. How can I initialize these higher addresses, at least in simulation? Thanks, laurent
