Can I declare a reg/logic using the generate if ... statement?Here is an example:generate if (L>0) reg pipe[W-1:0][L-1]; endgenerate...generateif (L==0) assign out[W-1:0] = in[W-1:0];else assign out[W-1:0] = pipe[L-1]; // <- error me...

Notice that the Assertion custom command is a valid SystemVerilog statement. The second assertion block is configured to output a warning with a specified message as shown below.If we run the model we can see that two assertion warnings are triggered in Simulink:...
Verilog Generate Loop The syntax for agenerate loopis similar to that of afor loopstatement. The loop index variable must first be declared in agenvardeclaration before it can be used. Thegenvaris used as an integer to evaluate the generate loop during elaboration. Thegenvardeclaration can be ...
in the case// statement that makes it a generate block/// Also notice how all the generate blocks are given the same// name `crc_poly` and all the function names are the same// `nextCRC16_D8`. This is correct because only one of the// function declarations is compiled in during el...
Foreach is a procedural programming statement that can only be used within a procedural block (eg. initial, always blocks). In this case, as @vivianyian0 suggested, you have to use "generate for". -Shreyas LikeReply1 like shaikon (Member) 4 years ago So I can put the "foreach" ...
Verilog generate statement is a powerful construct for writing configurable, synthesizable RTL. It can be used to create multiple instantiations of modules and code, or conditionally instantiate blocks of code. However, many Verilog programmers often have questions about how to use Verilog generate effe...

A generate statement is a concurrent statement used to create regular structures or conditional structures during elaboration. VHDL 2008 adds an else condition to if generate, and a new case generate. The examples in the design.vhd tab show three generate statements: 1. The first (lab...
