You can bit slice it with any range where the left index is higher than the right index. Swapping to have the right index larger than the left doesn't match the original definition. The LRM does discuss bit ordering of vectors somewhere, perhaps in section about bit slicing.

WebSystemVerilog Queue. A SystemVerilog queue is a First In First Out scheme which can have a variable size to store elements of the same data type. It is similar to a one-dimensional unpacked array that grows and shrinks automatically. They can also be manipulated by indexing, concatenation and slicing operators. WebThe goal is to design just one circuit that operate on any pair of bits, and then to replicate that exact same circuit n times. Figure 2. The overall 8-bit component is broken into eight identical bit slices. Designing a bit-slice circuit is a different task than designing the overall n-bit circuit, because the requirements are different for ...

Sorted by: 2. Keep a vector of 130 bits, and use it as a shift register. As you have to load at least 130 bits until you begin to process header and data, keep searching for the header at positions 128 and 129 of that vector (the two leftmost bit positions). When the header is detected, the next 128 bits already loaded in your 130 bit ... iris nichols hillsWebFeb 21, 2015 · 1. I have a FIFO which has a width 0f 32 and height of 32. 2.
