<4Gbps Low Power D2D Interface in TSMC 16nm & 28nm
A
Overview
A <4Gbps, Wide I/O Compatible, Die to Die Interface in TSMC 16nm and 28nm.
This silicon proven die to die interface includes IP in both TSMC 16nm FFC/FFC+ and 28nm HPM/HPC/HPC+. The I/O cells for both versions of the library are defined as TX only and RX only. The cells have two modes of operation: standard full rail to rail swing or a custom low noise psuedo-differential interface. The RX cells have a weak pull-down feature. The library is designed for Flip-chip/Die to Die packaging only, with no Wirebond option. Both library options have a common power bus architecture that when the cells are abutted, will feed through. There are no Power or Ground Pad/Cells, however all VDD and VSS connections will be made to the Core domain in upper metals. Both library options are ultra-low power, have a small footprint, MCM compliant, and have HBM & CDM robustness.

A Low-Leakage Digital Foundation for SkyWater 90nm SoCs: Introducing Certus’ Standard Cell Library
As semiconductor designs continue to diversify, many successful products are not chasing the most advanced process nodes. Instead, they prioritize power efficiency, reliability, and long-term availability.
Field Induced CDM Explained
Integrated circuits are commonly tested for ESD robustness with 2 tests, Human Body Model (HBM) and Charged Device Model (CDM). Most engineers quickly grasp the procedure for HBM, but the CDM test is often poorly understood. This is unfortunate, because a large fraction of the ESD failures experienced in modern board assembly operations are CDM type failures. This article will describe the events which occur during a CDM test conducted using the widely accepted field induced CDM (FCDM) test.
