New RTL Modeling Constructs in Verilog

October 16, 2025

I’ve been packing up my office as Siemens is closing my location. This marks the longest I’ve ever spent in a single office, a whopping 15 years. Coincidentally, I was in the same building earlier with another company, Avant! for an additional 2 years. I’ve got a box of stuff from previous jobs that I rarely unpack. But it happened to go through it and found the proceedings from what was to become the first DVCon in 1992. I doubt these proceedings exist anywhere in digital form.

In the proceedings was a paper I published about a new RTL modeling construct I added to Verilog before it became an IEEE standard. It eventually became known as a NonBlocking Assignment (NBA).

Interchange format standard in hierarchical CDC and RDC analysis

October 6, 2025

For large designs with numerous asynchronous clocks and resets, there is a growing need to do clock domain crossing (CDC) and reset domain crossing (RDC) analysis in a hierarchical way. This allows parallelization of sub-block and noiseless analysis and helps reduce SoC runtime and speed closure of CDC and RDC issues at the SoC level. Conversely, it poses challenges for design houses using third-party IP in ensuring the compatibility of their hierarchical data models (HDM) in the case of multiple EDA tools usage.

From manageability to 3.0: Unlocking the future with UCIe verification

September 26, 2025

The semiconductor industry is steadily moving toward multi-die integration, where chiplets from different sources are combined within a single package (known as a system in package or SiP) to deliver higher performance, scalability, and efficiency. The Universal Chiplet Interconnect Express (UCIe) standard is the backbone of this movement, offering a high-bandwidth, low-latency interconnect that enables heterogeneous chiplets to operate as one system.

UCIe 3.0 raises the bar once again. By adding higher data rates, runtime recalibration, priority sideband messaging, low-power sideband operation, and circular buffer transport, the standard improves both performance and efficiency. But it also increases verification complexity.
