Systemverilog cast bit width

WebOne way is to use a *bit width cast*: ```` F = (16' (A) * B) >> 8; ```` this forces 16-bit arithmetic to be used in the calculation, which is what is actually necessary. In Verilog (and hence … WebMay 29, 2024 · If the slice size would be 3, groups of 3 bits would be created starting from the least significant 3 bits. Since we have an 8-bit input value, the last (leftmost) group will contain the remaining 2 bits. No padding or truncation is performed. The bit group reversing would then be performed, leading to the output value 8’b100_001_10. 4.

Web7. SystemVerilog will resize numeric literals to the correct size following well-defined rules so its not necessary to define the size: logic [1:0] [BITWIDTH-1:0] x = ' {'h30, 'h40}; However, some tools do throw warnings so you can cast the literal to the right size like so: WebSystemVerilog Dynamic Cast When values need to be assigned between two different data type variables, ordinary assignment might not be valid and instead a system task called $cast should be used. $cast can be called as either a task or a function, the difference being that when used as a function, it returns a 1 if the cast is legal.

WebYou don't need to cast, you can use int type as normal 2 state bit vector with certain const length. The difference between then is int supports 2 states (0, 1), and logic supports 4 states (0, 1, x, z).
