Case Study 5 | UCIe & Chiplets

UCIe-Based Die-to-Die Interconnect Verification

Customer Semiconductor Mfr.
Aggregate Bandwidth 400G
Team Size 6 to 7 engineers
Duration 8 to 9 months

1 Challenge

A clean-slate custom die-to-die interconnect based on UCIe at 400G aggregate, with no existing verification infrastructure.

2 Approach

While a separate customer design team implemented the RTL, SNOVA built the UVM testbench from scratch along with a custom UVM VIP acting as the remote link partner.

3 Outcome

Complete testbench environment and remote link-partner VIP delivered over 8 to 9 months, achieving functional coverage closure.

4 Technical Scope

  • Custom UCIe-based die-to-die interconnect
  • 400G aggregate bandwidth
  • 56G x 8 lanes configuration
  • UVM testbench built from scratch
  • UVM remote link-partner VIP development
