How to define and initialize a vector containing only ones in …
So 0, which is a 32 bit constant, is first extended to the full 128 bit of mywire, then all the bits are flipped and the resulting all-ones vector is assigned. I'd prefer this version because it does not require you to specify the width of mywire anywhere in the assignment.

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:

verilog - Convert vector into array - Stack Overflow
Oct 24, 2016 · This will not work because Verilog requires both sides of the range to be constants (during simulation). There are three Verilog approaches to get the desired assignment: Bit assignment; Array slice assignment; Generate loop assignment; Bit assignment In Verilog-95 (IEEE1364-1995), the only ways achieve this was bit assignments with a double ...
How to declare and use 1D and 2D byte arrays in Verilog?
Dec 23, 2021 · But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with …
packed vs unpacked vectors in system verilog - Stack Overflow
A packed array is a mechanism for subdividing a vector into subfields which can be conveniently accessed as array elements. Consequently, a packed array is guaranteed to be represented as a contiguous set of bits.
verilog - What is the difference between single (&) and double ...
Jun 26, 2013 · This isn't quite correct. In Verilog, a vector (or any other) object is 'true' if it is non-zero, and it is known - in other words, it does not contain x/z metavalues. So, it's not 'tested for equality to 0'. @VL: try not to combine Verilog and SV questions - they're different languages. You wouldn't ask a C question in a C++ group, or vice-versa.

You may get warnings about operand being truncated to fit. But if vector is greater than 32 bits, bits starting from 32 will be x in your simulations.
