В среде MaxPlus все компилируется нормально, но в среде Quartus при компиляции возникает неразрешимая проблема типа

Понятно, что Quartus не хочет инициализировать память если we находится в непонятном состоянии.
Никакие ухищрения не помогают, кроме как посадить we на 0. Но в проекте we используется для последующей записи в RAM других данных.
Посоветуйте пожалуйста как быть, если без начальной инициализации RAM никак не обойтись.
