Throughout the process of physical design and verification there are many groups working on the design. Most often these groups are working independently or in parallel but separately, using their own specialized tools, such as P&R, DRC, custom layout, DFM, etc. At the end of the process there is an inevitable requirement… Read More
OK – maybe that sounds a little weird, but it’s not a bad description of what Mentor suggests in a recent white-paper. There are at least three aspects to power verification – static verification of the UPF and the UPF against the RTL, formal verification of state transition logic, and dynamic verification of at least some critical… Read More
In one of my whitepapers “SoCs in New Context – Look beyond PPA”, I had mentioned about several considerations which have become very important in addition to power, performance, and area (PPA) of an SoC. This whitepaper was also posted in parts as blogs on Semiwiki (links are mentioned below). Two important… Read More
Semiconductor based electronics has continuously improved lives of people through various kinds of technology upgrades in the gadgets for our daily use. Imagine the journey from a mechanical typewriter to a laptop computer connected through a laser printer, transition from black & white photography to exotic coloured… Read More
In today’s world where every device functions intelligently, it automatically becomes active on any kind of stimulus. The problem with such intelligence is that it can function unfavorably on any kind of bad stimulus. As the devices are complex enough in the form of SoCs (which at advanced process nodes are more susceptible to … Read More
SoC design these days has become a complex and tricky phenomenon involving integration of multiple IPs and legacy RTL code which could be in different languages, sourced from various third parties across the globe. Understanding and reusing RTL code is imperative in SoC integration which needs capable tools that can accommodate… Read More
Spice view of a design, block or fragment of the design is probably the lowest level of functional description of a circuit in terms of transistors, resistors, capacitors, interconnect and so on, which in several ways acts as an ultimate proof of pudding for any semiconductor design before manufacturing. However, it’s generally… Read More
In the semiconductor design industry, most of the designs are created and optimized at the RTL level, mainly through home grown scripts or manual methods. As there can be several iterations in optimizing the hierarchy for physical implementation, it’s too late to do the hierarchical optimizations after reaching the floor plan… Read More
As the SoCs and IPs grow in sizes and complexities, the number of formats, databases, libraries of standard cells and IOs also increase. It becomes a clumsy task to check every cell in a library, its consistency among various format with respect to functionality, timing, naming, labels and so on, and its complex physical properties… Read More
Although design houses have always strived for optimizing best design flows according to their design needs by customizing the flows using effective and efficient internal as well as external tools, this need has further grown in the context of design scenarios getting wider and wider from transistor, gate and RTL to system level.… Read More
