(Some early SystemVerilog simulators actually ignored the LRM and allowed dynamic dereferencing, but it was not LRM compliant). I have encountered this in the past, and I have mostly given up on arrays of interfaces; I use arrays of structures instead, but that means...

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 ...

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...
