1999.1b EXEMPLAR - Leonardo Spectrum is not inferring Xilinx Virtex flip-flops with enables


Keywords: flip, flop, enable, Virtex, logic

Urgency: Standard

General Description:
Version 1999.1b of Leonardo Spectrum does not infer Xilinx Virtex flip-flops with the enable pin. Instead, LUTs are used to implement the enable. This causes an increase in LUT count, and, therefore, area.


This has been fixed with the release of 2001.1a. If you do not have the latest version of Leonardo Spectrum, please download it from the Exemplar web site at:
