Lattice MACHXO3LF-6900C

I am working on a project to emulate a 1980s AM2764-A prom on an FPGA component (MACHXO3LF-6900C). I have created a project that works in simulation. However, when it comes to implementing it on the board, I am unable to manage the assignment of signals to pins, the creation of the clock, the management of timings, and the visualisation on the Lattice Diamond Reveal analyser.

I need help, please.
