WebI am new to indexing arrays in VHDL and there is a lot of information on online forums on how to access a bit in an element. However how do you access a group of bits in an array element. My guess would have been the following: declaration: type mem is array (0 to 7) of STD_LOGIC_VECTOR(255 downto 0); WebI don't know what your code is doing (I haven't fully reverse engineered it), but the normal solution is to unroll the bit assignment and do it bit by bit. So as an example if you had. a[index-1:0] <= b[index-1:0]; This would be illegal (if index was a reg/wire/signal) - the length of a[index-1:0] is not constant. You could, however, replace it ...

WebOct 25, 2016 · 1 Answer. You must index a slice with a usize. usize is an unsigned integral type that has the same size as a pointer, and can represent a memory offset or the size of an object in memory. On 32-bit systems, it's a 32-bit integer, and on 64-bit systems, it's a 64-bit integer. Declare your index variables as usize unless you really have a lot of ...
