M1.4 CPLD Hitop - Optimization disregards that control signals can have only 1 pterm.

説明

Keywords: 1.4, cpld, hitop

Urgency: Standard

General Description:

The M1.4 software collapses logic into control signals
disregarding that a control signal can have only 1 product
term. Additional internal nodes are created to implement
the collapsed logic. Each internal node occupies a macrocell
and for this design we run out of resources and can't fit the
design to the targeted device.

ソリューション

This problem is fixed in the latest M1.4 CPLD Patch available
on the Xilinx support website:
