XPLA Professional - Fitter continues when the number of PLA terms required is greater than resources allow.

Description

Keywords: XPLA, Professional, CoolRunner, fitter, PLA

Urgency: Standard

General Description:
Why does the fitter continue when the number of required PLA Product
Terms is greater than those available for the selected device?

解决方案

The PLA Product Terms can be shared among macrocells in the same
logic block. The fitter does not know how much sharing can be
accomplished until the fitter places and routes the design. Sharing
Product Terms can dramatically reduce the overall number of required
PLA Product Terms, thereby increasing logic resource efficiency.
