The semiconductor conference season has started out strong and the premier verification gathering is coming up at the end of this month. SemiWiki bloggers, myself included, will be at the conference covering verification so you don’t have to. Verification is consuming more and more of the design cycle so I expect this event to … Read More

Mentor’s Symphony in Tune with AMS Designer Needs
Mixed signal simulation is a very hot topic these days. In modern designs, it is harder to draw a line between the analog and digital and work with them independently. Analog blocks are showing up everywhere. Even in what would have qualified as a digital design a few years ago, now designers need to look at things like PLLs, IOs and … Read More
Portable Stimulus enables new design and verification methodologies
My usual practice when investing is to look at startup companies and try to understand if the market they are looking to serve has a significant opportunity for a new and disruptive technology. This piece compiles the ideas that I used to form an investment thesis in Portable Stimulus. Once collected, I often share ideas to get feedback.… Read More
Shifting Low Power Verification to an IP to SoC Flow
One of the most exciting recent developments in low power design and verification is the successive refinement flow developed by ARM® and Mentor Graphics®.… Read More
Something Old, Something New…EDA and Verification
When I got the opportunity to blog about verification, I thought, what new and interesting things should I talk about? Having started my EDA career in 1983, I often feel like one of the “oldies” in this business…remember when a hard drive required a static strap, held a whopping 33 MB, and was the size of a brick? Perhaps they should … Read More
Never Imagined So Easy Class-based Testbench Debugging
When it comes to debugging a design testbench organized in object-oriented style with objects, component hierarchies, macros, transactions and so on, it becomes an onerous, tasteless, and thankless task for RTL verification engineers who generally lag in software expertise. Moreover, class-based debugging tools have lagged… Read More
Power Management Gets Tricky in IP Driven World
Today, an SoC can have multiple instances of an IP and also instances of many different IPs from different vendors. Every instance of an IP can work in a separate mode and requires a dedicated power arrangement which may only be formalized at the implementation stage. The power intent, if specified earlier, will need to be re-generated… Read More
UVM Debugging Made Easy & Productive in Questa
As design complexity and size is increasing, SoC verification has become one of the most difficult and time consuming tasks in the design closure.UVM (Universal Verification Methodology, an accellera initiative) is one of the best verification methodologies that support common language, coherent strategy, clarity and transparency… Read More
Virtual Emulation Extends Debugging Over Physical
Amid burgeoning complexity of SoC verification with ever increasing hardware, software and firmware content, verification engineers are hard pressed with learning multiple tools, technologies and methodologies and still completing SoC verification with full accuracy in time. The complexity, size and diversity of SoC … Read More
Coverage Driven Analog Verification
Ad hoc digital design verification approaches ran out of steam at least a decade ago when designs got intractably large to make it feasible to keep track of everything with pen and paper and excel. But analog design has remained largely ad hoc to this day. The designer runs spice, looks at the waveforms that come out and decide whether… Read More
