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