Ports are connected in a certain order which is determined by the position of that port in the port list of the module declaration. For example, b in the testbench is connected to y of the design simply because both are at the second position in the list of ports. module mydesign ( ...
Hi, I was hoping someone could answer a fairly simple question. Here is my module declaration code for a transceiver design: module xcvr_prbs (
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...
通过X_INTERFACE_PARAMETER来修改信号的属性: // Declare the attributes above the port declaration(*X_INTERFACE_INFO="xilinx.com:signal:clock:1.0 <clock_port_name> CLK"*)// Supported parameters: ASSOCIATED_CLKEN, ASSOCIATED_RESET, ASSOCIATED_ASYNC_RESET, ASSOCIATED_BUSIF, CLK_DOMAIN, PHASE, FREQ_...
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 declaration to an actual net of the parent module. Is instantiated in another module. See the following coding example....

If your top level is VHDL, a component declaration is the most common way to specify this. However, if your top level is Verilog, you will need to supply a Verilog empty module corresponding to the lower level EDIF module (with matching ports) to satisfy the synthesis stub requirement. ...

the problem I stcuk is in the fpga_crossgen. the verilog declaration of my module is like this: ip_handler_top ip_handler_top_inst (// Interface: clock (clock end).clock ( ), // 1-bit clk input// Interface: reset (reset end).resetn ( ), // 1-bit reset_n input// I...
