I'm having some troubles in designing a 1-bit and 32-bit register in VHDL. Main inputs of the register include clock (clk), clear (clr), load/enable (ld) signals and an n-bit data (d). The n-bit output is denoted by (q). So far I believe to have made a 1-bit register, here is my code:

Under the assumption you want the counter to go from 0 to 9 and rollover this. if tmp = "1001" then # binary 9 tmp <= (others => '0'); # equivalent to "0000" else tmp <= tmp + 1; end if; And this emulates a synchronous load that takes priority over increment driven by an external 'state' recognizer. indian express live news
