times to do the shift and addition/subtraction in order to perform the multiply/division. Two's complement is assumed(ie, to negate a number, invert all bits and add 1). You may tailor it as needed for your own use. --- CUT HERE --- // Unsigned/Signed multiplication based on Patter...
Sometimes, you want to create a wide gate that operates on all of the bits of one vector, like (a[0] & a[1] & a[2] & a[3] ... ), which gets tedious if the vector is long. The reduction operators can do AND, OR, and XOR of the bits of a vector, producing one bit of...

Use a 32-bit wide XOR gate to invert the b input whenever sub is 1. (This can also be viewed as b[31:0] XORed with sub replicated 32 times. See replication operator.). Also connect the sub input to the carry-in of the adder. ...

19.Given five 1-bit signals (a, b, c, d, and e), compute all 25 pairwise one-bit comparisons in the 25-bit output vector. The output should be 1 if the two bits being compared are equal. out[24] = ~a ^ a; // a == a, so out[24] is always 1. ...
–scd_invert_queue:inverts order in which “same priority” events in the event queue are evaluated. –scd_randomize_queue: randomizes the order in which “same priority” events are evaluated. –scd_mtilike_queue:evaluates event queue similar to ModelSim/ActiveHdl. ...
Surely we need to "assign" F a value, so coding "assign F = " would be a good start... Ok, so A xnor B... We don't have an xnor symbol! No worries, we can make A XOR B then invert the entire term! This leads to a final solution of "assign F = ~(A ^ B);" ...
- All signals are lowercase alpha, numeric and underscore only. - Avoid active low signals in the core. If you must have them then append _b to the signal name. e.g. active_low_b (Active low signals at the pins is fine, but invert them in the core before using them) - Buses are...
