Embedded Multi-die Interconnect Bridge-T (EMIB-T) was a distinguished spotlight of the Intel Foundry Direct Join occasion. Intel is selling this superior packaging expertise as a key constructing block for high-speed chiplet designs and has partnered with main EDA and IP homes to speed up implementations round EMIB-T expertise.
Because the nomenclature exhibits, EMIB-T is constructed across the Embedded Multi-die Interconnect Bridge (EMIB) expertise, a high-bandwidth, low-latency, and low-power interconnect for multi-die silicon. EMIB-T stands for EMIB-TSV and it helps high-bandwidth interfaces like HBM4 and Common Chiplet Interconnect Categorical (UCIe). In different phrases, it’s an EMIB implementation that makes use of the through-silicon through (TSV) approach to ship the sign by means of the bridge with TSVs as a substitute of wrapping the sign across the bridge.

One other option to see EMIB-T is the mixture of EMIB 2.5D and Foveros 3D packaging applied sciences for prime interconnect densities at die sizes past the reticle restrict. Foveros is a 3D chip stacking expertise that considerably reduces the dimensions of bump pitches, growing interconnect density.
All three main EDA powerhouses have joined the Intel Foundry Chiplet Alliance Program, which is intrinsically linked to EMIB-T expertise. So, all three are working carefully with Intel Foundry to develop superior packaging workflows for EMIB-T. Begin with Cadence’s resolution, which helps streamline the combination of complicated multi-chiplet architectures.
Subsequent, Siemens EDA has introduced the certification of a TSV-based reference workflow for EMIB-T. It helps detailed implementations and thermal evaluation of the die, EMIB-T and package deal substrate, sign and energy integrity evaluation, and package deal meeting design package (PADK)-driven verification.
Synopsys can be collaborating with Intel Foundry to develop an EDA workflow for EMIB-T superior packaging expertise utilizing its 3DIC Compiler. Along with the EDA trio, Intel Foundry has engaged different gamers for EMIB-T assist. For example, Keysight EDA is working carefully with Intel Foundry to bolster the chiplet interoperability ecosystem.

The EMIB-T silicon bridge expertise is a significant step towards harnessing superior packaging for the quickly rising chiplets world. Intel Foundry Direct Join highlighted how the Santa Clara, California-based chipmaker sees this superior packaging expertise in its future roadmaps. Extra technical particulars about EMIB-T are more likely to emerge later in 2025.
