## [moved] Need VHDL code for floating point multiplier

Unfortunate the floating point vendor libraries aren't provided as VHDL sources, most likely they even haven't been written in VHDL or verilog. They are designed to use the DSP hardware of different FPGA families in an optimal way, using respective low-level primitives. Altera e.g. is typically writing this stuff in AHDL. for the same (...)

## Designing a 2's Complement Multiplier

Hi Digit0001, I'm not so familiar with VHDL but in verilog I can use signed singals to do twos complement multiplication without checking the sign bit. see example module tb (); reg signed mcand; reg signed mplier; wire signed result; initial begin // -80 x -32 mcand = 8'b

## verilog hdl program code

sum={A,Q}; sum is an output and A,Q are both inputs. Other than this, the code listed is probably a poor choice. Its best to avoid "while" in synthesized code -- it more used for testbenchs. "for" is a better choice, but keep in mind that real iterations will cause complexity to grow quickly. for (...)
