FPGA Express 3.1: Virtex: May not always infer the MUXF5 / MUXF6

説明

Keywords: FPGA Express, 3.1, 3.2, Virtex, MUXF5, MUXF6, 5 input function, 1 slice

Urgency: Standard

General Description:
FPGA Express 3.1 (Foundation Express 1.5i Service Pack 1) has the ability to infer the MUXF5,
but not the MUXF6. FPGA Express 3.2 (Foundation Express 2.1i) has the ability to infer the MUXF5
and MUXF6. These components can be instantiated in any 3.x version of FPGA Express.

ソリューション

There are certain cases where a five (or six) input functions could use these special components
but do not. If you have a design that you feel should use these resources but do not, please bring
this to the attention of the Synopsys Hotline (if you are an Alliance customer) or the Xilinx Hotline
(if you are a Foundation customer).
