UVM based Verification of a Wireless Charger SOC

Background

The client is one of the world’s leading suppliers of a wide range of analog,  MEMS and sensor semiconductors.

The scope of the project was to undertake the hardware verification of a wireless charger SOC comprising an ARM Cortex M4 core, ROM, SRAM and enhanced peripherals including I2C, SPMI, PWM timers, IO  ports and a ADC interface.

The T&VS Solution

T&VS undertook the project using the Universal Verification Methodology (UVM) using the Cadence Incisive and vManager Tools.

The verification process included:

  • Performance testcases for I2C, SPMI, CM4, DMA; all programmed to same time. (Multi master)
  • C test and UVM test Synchronization
  • Isolated crypto and integrated crypto testing with Golden reference model integration
  • Integration of C-based fixed point Models for DSP blocks
  • RAL Model Integration for Register Verification,Default Value check, Bit bash testing,walk through ones,zeros through AHB,I2C and SPMI masters
  • A scoreboard at SOC level to collect the transmitted data from the monitors and check the data integrity and all register read write and connectivity check
  • Code coverage for the full SOC level
  • End to End testcases

Benefits of T&VS Solutions

  • An independently verified SOC that meets the requirements of the customer’s tier 1 consumer electronics OEM.
