How to compare two numbers (nets, variables, constants) in Verilog

WebIn Verilog we design modules, one of which will be identified as our top-level module. Modules usually have named, directional ports (specified as input, output or inout) which are used to communicate with the module. In this example the module’s behavior is specified using Verilog’s built-in Boolean modules: not, buf, and, nand, or, nor, xor, WebOct 28, 2024 · Trophy points. 1.

WebMay 21, 2024 · SystemVerilog Bit Wise Operators We use the bit wise operators to combine a number of single bit inputs into a single bit output. In addition. We most commonly use the bit wise operators to model logic gates in SystemVerilog. The table below shows the full list of bit wise operators which we can use in SystemVerilog. WebAn integral part of subtraction in logic systems is the use of two’s complement. This enables us to execute a subtraction function using only an adder rather than requiring a separate subtraction function. Two’s complement is an extension to the basic ones’ complement (or basic inversion of bits) previously considered.

For each step, we shift the left-most digit of the dividend A into ACC, then compare it with the divisor B. If ACC is greater or equal to B, then we subtract B from ACC and add 1 to the quotient QUO. This is easiest to see by working through the example:
