5 2 1 Vector bit-select and part-select addressing Bit-selects extract a particular bit from a vector net, vector reg, integer, or time variable, or parameter The bit can be addressed using an expression If the bit-select is out of the address bounds or the bit-select is x or z , then the value returned by the reference shall be x A bit-select or part-select of a scalar, or of a variable
- What is the difference between == and === in Verilog?
Some data types in Verilog, such as reg, are 4-state This means that each bit can be one of 4 values: 0,1,x,z With the "case equality" operator, ===, x's are compared, and the result is 1 With ==, the result of the comparison is not 0, as you stated; rather, the result is x, according to the IEEE Std (1800-2009), section 11 4 5 "Equality operators": For the logical equality and logical
