relational operator Definition
A comparator, called a "relational operator" in VHDL and Verilog HDL, is an operator used to compare nodes, groups, and numbers. AHDL, VHDL, and Verilog HDL provide the following comparators:
| Comparator | Definition | 
|---|---|
| > | greater than | 
| < | less than | 
| <= | less than or equal to | 
| >= | greater than or equal to | 
AHDL and VHDL provide these additional comparators:
| Comparator | Definition | 
|---|---|
| == | equal to (AHDL only) | 
| = | equal to (VHDL only) | 
| != | not equal to (AHDL only) | 
| /= | not equal to (VHDL only) |
