If. you simply. assign the value of the integer to a reg array, it automatically. casts the. integer to reg type according to the rule of right. justification (I do not. remember which chapter of IEEE 1364 discusses this, but look for. the one which talks about the variables.)
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). So if you want to XOR 8 bits of int A and logic [7:0] B, you can: A [7:0] ^ B Chris Le yourcheers Full Access 107 posts March 28, 2024 at 11:31 pm WebMar 24, 2024 · It's just there are different places where constant expressions are required, the the bit-width of a variable declaration is one of them. In C, you cannot use a const variable to declare the size of a static array, but you can for a non-static array. \$\endgroup\$ –
WebFeb 2, 2024 · The verilog replication operator will work here. The general syntax is: {n {m}} ( m will be replicated n times). The replication count, n, must be a constant value, and can be a parameter value.
