we can performe some simple conditional statments and decition directly in architecture, in some case it might be preffer over using a process, for small cases for decition we would use when statment.
syntax
signal\output <= value when boolean condition else value2;
full Example from right.
Below are 2-bit comperator with compare 2 bit inputs, and have 2 outputs, one to define if A > B or not. and the second to define if they equal.
Simulation done with TCL script that tests the desired behaves A > B, A < B, A = B.
we can see the waveform behaive as expected..
Note that system behaive same like this.
