The full-chip support includes test-chip support with flexibility to work effectively with extended hours with world-wide customers.
Further to the above, KarMic offers SOC integration support.
- Verification:KarMic has over 14+ years of experience in the top-level mixed signal SOC verification. Have helped customer specific mixed signal SOC verification flow development which is being extensively used for verification and has resulted in highly functional first pass silicon.
KarMic Team works on full chip verification which involves RTL/Gate-level verification of digital and schematic verification of Analog modules in a top level mixed-signal environment.
We develop functional models for Analog blocks using VHDL RN, wreal or vams modeling concepts.
We study the specifications and come up with a simulation plan for both RTL verification as well as Analog module verification from top-level perspective.
We set up test-bench and build test cases to verify the scenarios mentioned in simulation plan using SV and UVM concepts. Report any bugs found in design to Digital design/Analog design/ System design teams.
In addition to reporting bugs, the team also debugs RTL issues, hook-up issues and schematic issues and report the root cause for bugs to design team.
We track all the bug fixes, and follow-up with design team until there is closure on all the bugs and the fixes are verified again.
Apart from the above; we execute CODE coverage to ensure good RTL coverage in top level simulations. We run Gate level simulations with SDFs included and look for any timing violations. We effectively track the simulation plan coverage, report status and review results with customer to ensure good quality first pass silicon. We also deliver procedures to TEST team for post-silicon validation.
- AMS Verification Training: We have tie-up with MIT to use Cadence tool at their labs for layout, simulations and AMS verification. The training includes:
- Verilog training: Includes modeling and verifying combinational, complex combinational, sequential logics, memories, interface protocols like I2C.
- Verilog AMS Training: Includes modeling wreal and electrical models for a few Analog blocks like LDO, BUCK, PLL and ADC.
