blocklyTB is a visual programming tool for writing Verilog testbench. It is based on the secondary development of Google Blockly and assists learning FPGA for educational purposes.
You can access and use it online, but first make sure that you already have the FPGA design file (file ending in .v) or the xml design file exported by blocklyTB.
You can also save the link as a favorite for future visits.
Of course, you can also get the source code locally, visit blocklyTB/index.html in your browser to use.
Theses are the main features of blocklyTB:
- Supports most Verilog syntaxes, enabling basic testbench design.
- Supports automatic DUT instantiation. Just upload the completed FPGA design (only Verilog language is supported), blocklyTB will automatically complete the instantiation process required by the testbench.
- Supports to save the design of blocklyTB locally. you can import it again to continue the design next time.
- Can create different types of variables, such as reg, wire, parameter, localparamter, integer, etc.
- Implemented encapsulation and reuse of the task.
- blocklyTB adds several system functions commonly used in Verilog, such as $ time, $ monitor, $ random, etc., and common file I/O functions.
- Generate corresponding Verilog code in real time and display it in format, which can be copied or downloaded.
- Some other features provided by Google Blockly.
