The genvar declaration can be inside or outside the generate region, and the same loop index variable can be used in multiple generate loops, as long as the loops don’t nest. The genvar is used as an integer to evaluate the generate loop during elaboration. The loop index variable must first be declared in a genvar declaration before it can be used. The syntax for a generate loop is similar to that of a for loop statement. For readability, I like to use the generate and endgenerate keywords. Generate regions can only occur directly within a module, and they cannot nest. If they are used, then they define a generate region. Use of the keywords generate and endgenerate (and begin/ end) is actually optional. This sometimes causes confusion when trying to write a hierarchical reference to signals or modules within a generate block, so it is something to keep in mind. For example, generate constructs can be affected by values from parameters, but not by dynamic variables.Ī Verilog generate block creates a new scope and a new level of hierarchy, almost like instantiating a module. Therefore all expressions within generate constructs must be constant expressions, deterministic at elaboration time.

Verilog generate constructs are evaluated at elaboration, which occurs after parsing the HDL (and preprocessor), but before simulation begins. Conditional generate constructs include if-generate and case-generate forms.
CAN WE ASSIGN NAME TO FOR LOOP IN R CODE
Conditional generate constructs select at most one block of code between multiple blocks. Generate loop constructs allow a block of code to be instantiated multiple times, controlled by a variable index. There are two kinds of Verilog generate constructs. In this article, I will review the usage of three forms of Verilog generate-generate loop, if-generate, and case-generate.
CAN WE ASSIGN NAME TO FOR LOOP IN R HOW TO
However, many Verilog programmers often have questions about how to use Verilog generate effectively. It can be used to create multiple instantiations of modules and code, or conditionally instantiate blocks of code. Verilog generate statement is a powerful construct for writing configurable, synthesizable RTL.
