Signed comparison in Verilog¶ When you write this in Verilog: wire [7:0] a; wire [7:0] b; wire less; assign less = (a < b); the comparison between a and b is unsigned, that is a and b are numbers in the range 0-255. Writing this instead: wire [7:0] a; wire [7:0]...
This starts with a bug in my nMigen -- I perform a comparison between unsigned and signed values. If this means behavior is undefined, then we can just close this issue. It seems that simulation treats this as an unsigned comparison, while the generated Verilog has a signed comparison. On...

Verilog math operations and comparison operations (such as the less-than and greater-than operators) use the data type of the operands to determine whether to perform signed or unsigned operations. The general rule is that if all operands in the expression are signed, then a signed operation ...
By employing these Veda ganitha sutras in the computation algorithms of the ALU, the complexity, execution time, area, power etc can be reduced. In this work, Verilog HDL has been used to code the a...
The coding is done for 16 bit (Q15) and 32 bit (Q31) fractional fixed point multiplications using Verilog and synthesized using Xilinx ISE version 12.2. Further the speed comparison of this multiplier with normal booth multiplier and Xilinx LogiCore parallel multiplier Intellectual Property (IP) ...
