There's a divide function declared in IEEE package that demonstrates the correct arithmetic for finding the bounds of the divide operator: -- ufixed (a downto b) / ufixed (c downto d) = ufixed (a-d downto b-c-1) And because the rules for bounds can be complex there are functions (ufixed_high, … Web31 de oct. de 2013 · What the above code does is simply that it creates a VHDL module containing a 24 bit counter q, which is counted up on each rising edge from the master clock mclk. It then derives clk190 and clk48 by using different bits of this counter directly as clock signals. For instance, with mclk at 50 MHz, the lsb (q(0)), would effectively run at 25 MHz. massachusetts open the books hydralians rochefort
