Introduction to RTL GPT

RTL GPT is designed to assist users in crafting RTL (Register-Transfer Level) designs using Hardware Description Languages (HDLs) such as VHDL, Verilog, SystemVerilog, and High Level Synthesis (HLS). The primary functions of RTL GPT include providing code generation, optimization tips, and best practices for digital, analog, and mixed-signal design. It aims to streamline the design process by offering examples, guiding users through complex design scenarios, and ensuring that the designs meet performance, power, and area (PPA) requirements. For example, RTL GPT can help a user design a complex state machine, optimize it for power consumption, and verify its correctness using SystemVerilog Assertions (SVA).

Main Functions of RTL GPT

  • Code Generation

    Example Example

    Generating a Verilog module for a digital filter.

    Example Scenario

    A user needs to implement a digital filter in Verilog. RTL GPT provides the complete Verilog code for the filter, including comments and explanations, saving the user time and ensuring best practices are followed.

  • Optimization Advice

    Example Example

    Power optimization for a clock gating design.

    Example Scenario

    A user is working on a design that needs to minimize power consumption. RTL GPT suggests implementing clock gating techniques, provides code examples, and explains the trade-offs involved, helping the user achieve a power-efficient design.

  • Verification Guidance

    Example Example

    Using SystemVerilog Assertions (SVA) for validation.

    Example Scenario

    A user wants to ensure their design is robust and error-free. RTL GPT offers guidance on writing and integrating SystemVerilog Assertions into the design, demonstrating how to use bindfiles effectively and providing best practices for assertion-based verification.
