GPIO Verification IP

Truechip’s GPIO Verification IP offers a streamlined and efficient solution for verifying GPIO components within an IP or SoC. Truechip's VIP fully adheres to the GPIO Specification version 2.0 and features a lightweight, plug-and-play design, ensuring that it does not impact the design cycle time.

Key Benefits

• Available in native System Verilog (UVM/OVM/ VMM) and Verilog
• Unique development methodology to ensure the highest levels of quality
• Availability of Compliance & Regression Test Suites
• 24X5 customer support
• Unique and customizable licensing models
• Exhaustive set of assertions and coverage points with connectivity example for all the components
• Consistency of interface, installation, operation, and documentation across all our VIPs
• Provide complete solution and easy integration in IP and SoC environment

Features

• Each GPIO pin can be individually configured as input, output, or bi-directional.
• Allows receiving data from external sources, sends data to external devices and can act as both input and output based on control signals.
• Verification of GPIO signal levels (e.g., high, low, tri-state)
• Optimized for low latency and high throughput.
• Supports standard GPIO protocols, such as simple input, output, and bi-directional communication.
• Detects signal changes on both rising and falling edges.
• Supports variable bit-width configurations for the number of GPIO pins.
• Configurable sampling frequency to control the timing of reading the GPIO signals.
• Verifies the state of GPIO pins during input, output, and interrupts.
• Supports integration into verification environments like UVM (Universal Verification Methodology).
• VIP can verify wake-up functionality from a low-power mode based on external GPIO signals.
• Allows the introduction of errors such as glitch, stuck-at, and short-circuit conditions to test the robustness of the GPIO logic
• Provides detailed logging of GPIO transactions and state changes for debugging purposes.
• Models interrupt pin behavior with active-high, active low, and edge-triggered configurations.
• Supports testing GPIO-based events like power-on, reset, or system interrupts.
• TheVIPcanscale to verify designs with a large number of GPIO pins, ranging from a few to hundreds of GPIO signals.
• If the GPIO pins are multiplexed with other interfaces like SPI or I2C, the VIP can simulate these conditions.
• Allows verification of designs where multiple GPIO controllers or blocks are present.
