KEY FEATURES

STIMULUS

· 400+generationconstraintsenable targeting of coverage holes

Cadence® Incisive® Verification IP for the MIPI® DSI enables metricdriven verification, resulting in comprehensive verification of IP and SoC designs against the protocol specification. Real-time graphical presentation of verification coverage vs. plan boosts confidence in your design and removes the guesswork from knowing when it's time to tape out. As with all of the 30+ protocols in the Incisive VIP Portfolio, MIPI DSI VIP offers OVM multi-language support (SystemVerilog and e) to facilitate collaboration across projects. Cadence is proud to be a Contributing Member of the MIPI Alliance.

FOCUS ON VERIFICATION

IncisiveVerificationIPisindependentlycreatedandtestedagainstexternaldesignIP sources to provide fully objective validation. This focus prevents the bug transfer that can occur when design IP and verification IP are co-developed.

COMPLIANCE MANAGEMENT SYSTEM (CMS)

The CMS provides a protocol-specific metric-driven verification environment that includes: · Executableverificationplan(vPlan) - Matches protocol specification · Libraryofconstrained-randomtests - IsolatesDUTcornercases · Integratedcoveragemodel - Gradesverificationcompleteness · Compliancechecksandmetrics - IdentifiesDUTverificationgaps

Compliance vPlan Compliance Test Suite

VERIFYING PROCESSOR MODELS

The Incisive UVC verifies the DUT by providing an active peripheral agent to assemble packets, and a passive monitor agent for protocol checking and coverage collection. The active peripheral supports all protocol features including: · Configurationsof1to4virtual channels · AllDSIpackettypes · Packeterrordetection · Receivingmultiplepackettypesinthe same high-speed transmission · Commandmodesupport · Videomodesupport - Non burst with sync pulses - Non burst with sync events - Burst mode

VERIFYING PERIPHERAL MODELS

The Incisive UVC for MIPI verifies the DUT by providing a DSI active processor agent to generate stimuli and a passive monitor agent to check the protocol and collect coverage. Constraints provide for stimulus tuning at the packet level for all operating modes. The active transmitter supports all protocol variations: · Supportfor4virtualchannels · Datatransmissionon1to4lanes · Packeterrorinjection - Reserved and unsupported data types - 1bit,2bit,multi-bitECC - Word count - Checksum - Pixelalignment - Byte count · PHYerrorinjection - High-speedsynchronization - Low-power control
