Problem Title:
ngdbuild: Unexpanded blocks.  Design from Exemplar Leonardo.


Problem Description:
keywords: Unexpanded, blocks, EQN

Uregency: Standard

General Description:

NGDBUILD issues warnings about blocks of type EQN are unexpanded.


Solution 1:

For xc4000 designs EQN blocks are not supported.  By default, Leonardo synthesiz
es to LUTs (EQN blocks).  To map these LUTs to gates within Leonardo use the com
mand "decompose_luts".
