Introduction

In the world of digital design, debugging is a crucial step that can make or break the success of a project. With the increasing complexity of modern designs, traditional simulation-based debugging methods are no longer sufficient. This is where the Synopsys Identify RTL Debugger comes into play. In this article, we will delve into the world of RTL debugging and explore the features and benefits of the Synopsys Identify RTL Debugger.

What is RTL Debugging?

RTL (Register-Transfer Level) debugging is a method of debugging digital designs at the RT-Level, which is the level of abstraction between the behavioral and structural levels. At this level, the design is described in terms of registers and their interactions, making it an ideal level for debugging. RTL debugging allows designers to identify and fix errors in the design before it is implemented on hardware, reducing the time and cost associated with re-spinning the design.

The Synopsys Identify RTL Debugger

The Synopsys Identify RTL Debugger is a powerful tool that allows designers to instrument RTL HDL and debug the implemented FPGA on live, running hardware. This debugger verifies a design in hardware, similar to simulation, but much faster and with in-system stimuli. The Identify RTL debugger allows designers to designate sample triggers, navigate the design graphically, and mark signals in the RTL that are to serve as probes.

Key Features of the Synopsys Identify RTL Debugger

Instrumentation of RTL HDL: The Identify RTL debugger allows designers to instrument RTL HDL, which enables the debugger to collect data and provide insights into the design's behavior.
Debugging on Live, Running Hardware: The debugger allows designers to debug the implemented FPGA on live, running hardware, which reduces the time and cost associated with re-spinning the design.
In-System Stimuli: The Identify RTL debugger provides in-system stimuli, which enables designers to test the design with real-world inputs and verify its behavior.
Graphical Navigation: The debugger allows designers to navigate the design graphically, which makes it easier to identify and fix errors.
Signal Probing: The Identify RTL debugger allows designers to mark signals in the RTL that are to serve as probes, which enables them to collect data and provide insights into the design's behavior.
