- 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

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

The lesson is to use the reg wire types in classic Verilog, or the bit logic types in modern Verilog, and size your signals appropriately (Be warned, those types aren't equivalent)

Description and examples can be found in IEEE Std 1800-2017 § 11 5 1 "Vector bit-select and part-select addressing" First IEEE appearance is IEEE 1364-2001 (Verilog) § 4 2 1 "Vector bit-select and part-select addressing" Here is an direct example from the LRM: logic [31: 0] a_vect; logic [0 :31] b_vect; logic [63: 0] dword; integer sel; a_vect[ 0 +: 8] == a_vect[ 7 : 0] a_vect[15 -: 8
