All port declarations are implicitly declared aswireand hence the port direction is sufficient in that case. Howeveroutputports that need to store values should be declared asregdata type and can be used in a procedural block likealwaysandinitialonly. ...

For example, design modules are normally instantiated within top level testbench modules so that simulation can be run by providing input stimulus. But, the testbench is not instantiated within any other module because it is a block that encapsulates everything else and hence is thetop-level mod...
Verilog generate block, that do not have a name label, creates a hierarchy that is only visible within the block, and within the sub-tree formed by this block—and nowhere else. Therefore it’s good practice to always name Verilog generate blocks so all identifiers can be referenced througho...

A behavioral Verilog module instantiation statement does the following: Defines an instance name. Contains a port association list. The port association list specifies how the instance is connected in the parent module. Each element of the port association list ties a formal port of the module ...
You can clearly see that the instance dff_vhdl is not properly declared. The instance name is missing. This will generate an Error similar to the following: Starting static elaboration ERROR:HDLCompiler:1654 - "C:/Users/ppopescu/Desktop/hydra_PP/mixed_verilog_vhdl_example/sources/encapsulated_mi...
After generating the .qsys file when I am trying to run the top module verilog file in quartus II it is giving error :Error (10228): Verilog HDL error at gmmpipe.v(6): module "gmmpipe" cannot be declared more than once. I gave gmm_accelerator.v and gmmpipe.v module during ...
It came to my attention when I tried some Verilog code, that Quartus synthesis and Modelsim do not deal with Verilog 2005 in the same way when it comes to defining local parameters in the port parameter declaration list. The reason why I wanted this is very simple: To...
The code as written compiles without errors in both Modelsim and Vivado, so I'm not sure why your are saying line 22 has an error. You do have other issues in this code that need to be addressed. Your reset rst in ClockDivider is declared as an output, so nothing is driving the re...
