I The multiplication operator in Verilog is leads to what is called a context determined expression The width used for the arithmetic in a self determined expression depends on the widths of the operands and the result With assign c a b the width used for the multiplication will be the widest of a b and c Signed Multiplication Multiplying Numbers Of Different Sizes . Jun 1 2018 nbsp 0183 32 I was right there with you until the last paragraph If you don t realize that multiplication is repeated addition then either you haven t taken grade school math or you haven t really internalized the concept of breaking a problem down to its smaller components If it s the latter that s actually a bit of a flag Like described in the title is there some library in the Microsoft framework which allows to multiply two matrices or do I have to write my own method to do this
