Best in class MIPI® I3Csm Verification IP for your IP, SoC, and system-level design testing.

In production since 2015 on dozens of production design.

The Cadence® Verification IP (VIP) for MIPI® I3Csm VIP provides support for the MIPI I3C protocol specification. It provides a mature, highly capable compliance verification solution that supports simulation, protocol checking, coverage collection, and analysis, making it applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP for I3C helps you reduce time to test, accelerate verification closure, and ensure end-product quality. The VIP runs on all major simulators and supports SystemVerilog and e verification languages along with associated methodologies, including the Universal Verification Methodology (UVM) and Open Verification Methodology (OVM).

The I3C Specification describes the I3C interface (Improved Inter Integrated Circuit), which is used for easing sensor system design architectures by providing a fast, low-cost, low-power, two-wire digital interface for sensors.

Supported Specifications: MIPI I3C specification v1.0, v1.1, and v1.01. MIPI I3C Basic specification v1.0 and I2C specification.

MIPI I#C

Product Highlights

  • Support testbench language interfaces for SystemVerilog, UVM, OVM, e, and SystemC
  • Contains predefined checks to verify that the DUT agents adhere to the supported protocol features
  • Generates I3C traffic as single or multi-agent driving with the ability for constrained-random bus traffic
  • Provides ability to generate intentionally erroneous traffic on the bus
  • Callbacks access at multiple TX and RX queue points for scoreboarding and data manipulation
  • Packet tracker creation for easy debugging
  • Provides extensive coverage in e and SystemVerilog
