The Logic Section specifies the logical operations of the Text Design File (.tdf). This section is required. One or more of the following statements or constructs may be used in this section:
END keywords enclose the Logic Section. A semicolon (
;) follows the
END keyword and terminates this section. The Defaults Statement must be the first statement in the section.
||AHDL is a concurrent language. The Compiler evaluates all behavior specified in the Logic Section of a TDF at the same time rather than sequentially. Equations that assign multiple values to the same AHDL node of type
NODE or variable are logically ORed or ANDed. See Boolean Equation Rules or Defaults Statement Rules for more information.
