3D IC Design Suite

by Bryon Moyer

There’s lots of talk about 3D (and 2-1/2-D) ICs, with through-silicon vias (TSVs) being a key enabling technology. The possibilities are exciting, but the reality also appears to be challenging. Costs are high, there are still reliability questions to answer, and the overall design flow has yet to be thoroughly established. Even just simple questions like place and route have been the subject of early projects (involving at least one company that’s no longer in business).

Synopsys has recently announced their 3D-IC Initiative, essentially a collection of their EDA tools focused on hacking a flow through this technology jungle. It includes digital and custom design support, test, parasitic extraction, memory compilation, simulation, and more. All of which are impacted by 3D IC design.

Even though you might wonder, “How hard can it be to stack one die on top of another?” the answer appears to be, “Pretty hard.” At least until the tools settle down to make it easier.

More details in their release…

PCIe Gen5 x16 Running on the Achronix VectorPath Accelerator Card

Sponsored by Achronix

In this demo, Achronix engineers show the VectorPath Accelerator Card successfully linking up to a PCIe Gen5 x16 host and write data to and read data from GDDR6 memory. The VectorPath accelerator card featuring the Speedster7t FPGA is one of the first FPGAs that can natively support this interface within its PCIe subsystem. Speedster7t FPGAs offer a revolutionary new architecture that Achronix developed to address the highest performance data acceleration challenges.

HARTING's HAN® 1A Connector Series

Sponsored by Mouser Electronics and HARTING

There is a big push in the electronics industry today to make our designs smaller and more modular. One way we can help solve these design challenges is with the choice of connector we select for our designs. In this episode of Chalk Talk, Goda Inokaityte from HARTING and Amelia Dalton examine the role that miniaturized connectivity plays in the future of electronic design. They also how HARTING's Han 1A connectors can help reduce errors in installation, improve serviceability and increase modularity in your next design.
