Thestd_ulogicis simply an enumerated type that lists the possible values as enumeration literals. When a signal or variable is declared withstd_ulogicas the type, it can represent any one of these values and none other. The'U'value is the first of the listed values. That’s the reason ...
performs differently than you intended. When using numeric_std, you arenot allowedto perform any mathematical operations on signals unless you have first declared them as either typesignedorunsigned. Therefore in the example above, if count is always a positive number, you should declare it as ...

I have mixed language environment (simulation of mixed VHDL and Verilog) and would like to pass STD_LOGIC generic parameter from Verilog code where this VHDL module is instantiated.VHDL generic parameter is declared:generic(
Signal Slv2 was declared using an initial value of all 0’s. Instead of specifying the exact value for each bit, we used (other => '0') in place of the initial value. This is known as an aggregate assignment. The important part is that it will set all bits in the vector to whate...
I'm VHDL beginner working on a Filter code, which is shown below and i'm getting the error as "error (10482): vhdl error at fir.vhd(17): object "std_logic_signed" is used but not declared" but i believe i included proper libraries , please help me so...
If you find that division is not performed in your code, then check if there is some optimizations. Before that, check if you have declared the range on the integer signals appropriately. Is it possible to get the complete code, if you feel everything is alright in the design? Upvote 0...
