This tutorial uses the IGLOO nano Starter Kit and AGLN250 device, but the same design could be ported to a different development board with slight changes in pin assignments. Also, note that the `ifdef macro configuration is coded as part of the model. For DV engineers with a background in Functional Verification (UVM), getting started on Formal Verification can seem overwhelming and a steep hill to climb. Here's an example: systemverilog. Verilog supports a few compiler directives that essentially direct the compiler to treat the code in a certain way. we will show how you can create a macro from a Verilog (. v), abstract logical, timing, power view (.

Debugging. by: EDA Playground This tutorial covers Verilog design, simulation, waveform viewing and debugging. It is a compiler directive that enables developers to define reusable code snippets or constants that can be easily referenced throughout the design. Nov 23, 2016 · Creating Macros from Verilog. Formal Verilog configurations were added as part of Verilog 2001 and then updated/enhanced with the SystemVerilog generations of the language [2, 3]. Once you've defined a macro, you can use it elsewhere in your code. For example, a portion of the code may represent an implementation of a certain feature and there should be some way to not include the code in the design if the feature is not used. The `else is not required, but `endif must complete the conditional statement. Byte and int are directly compatible with C, while the packed array is redefined using the macro SV_BIT_PACKED_ARRAY(width, name). Mar 20, 2021 · Macro can call other macros or compiler directives, but be careful, should keep it simple.
