Hello, I'm using some binding modules in sytemverilog VIP. They are binded to VHDL modules. The systemverilog modules' ports are all defined as logic without specifying direction (input, output or inout). Compilation passes without any errors. Elaboration fails. It requires direction to be spec...
SystemVerilog has an interface construct that allows you to bundle up common signals in a single port declaration. This avoids repeated declaration and connection of signals. SystemVerilog also has a .* (dot-star) construct that automatically connect signals with ports having the same name. Sup...
Both modules are saved and compiled as SystemVerilog veiws in Cadence Virtuoso and symbols are instantiated in a schematic view. On simulating this in a test bench, I notice that the config view doesn't recognize the SINE module! Hence, I get this error...
首先需要找到C盘中的verilog.json文件,路径通常为C:\Users\Admin.vscode\extensions\mshr-h.veriloghdl-1.5.11\snippets,不同的电脑用户名位置处不一样。 打开verilog.json文件,如下图所示,当输入prefix后面引号里的文字后,就能选择出body对应的代码片段,在body代码片段里,每行代码需要包含在双引号里,句末加逗号,\...
SystemVerilog的接口(interface)允许我们将信号声明信息封装于一个地方。下例同上例一样,只是用了interface。现在如果要在两个模块间添加一个信号,或事更改向量长度(size)的话,就只需要修改一处代码了。 interfaceintf_1;wiresig1,sig2,sig3,sig4;endinterface:intf_1moduletop;wireclock,reset;intf_1i1();mod...
ModelSim 20.1.1: The simulation runs successfully, producing an output. However, this behavior is incorrect as nested modules are not allowed in Verilog. QuestaSim: When I ran the same code in QuestaSim, it correctly reported the error:"Module '...

Our code is written in standard SystemVerilog (IEEE 1800-2012, to be precise), so the more important question is: Which subset of SystemVerilog does your EDA tool support?We aim to be compatible with a wide range of EDA tools. For this reason, we strive to use as simple language ...
