Mentor Wins v Synopsys

Mentor Wins v Synopsys
by Paul McLellan on 10-15-2014 at 10:00 am

Just a couple of days ago I read a curious press release.Mentor Graphics Corp. (NASDAQ: MENT), today announced that a Portland, Oregon jury delivered a verdict in favor of Mentor in a trial in which Mentor asserted infringement of one of its patents against Emulation and Verification Engineering S.A. (EVE) and Synopsys, Inc. (Nasdaq:Read More


A Complete Timing Constraints Solution – Creation to Signoff

A Complete Timing Constraints Solution – Creation to Signoff
by Pawan Fangaria on 09-28-2014 at 10:00 pm

With the unprecedented increase in semiconductor design size and complexity design teams are required to accommodate multiple design constraints such as multiple power domains for low power design, multiple modes of operation, many clocks running, and third party IPs with different SDCs. As a result timing closure has become… Read More


Synopsys Verification Continuum

Synopsys Verification Continuum
by Paul McLellan on 09-26-2014 at 4:00 pm

Verification spans a number of different technologies, from virtual platforms, RTL simulation, formal techniques, emulation and FPGA prototyping. Going back a few years, most of these technologies came from separate companies and one effect of this was that moving the design from one verification environment to another required… Read More


Transceiver Verification of a 20nm Altera FPGA Device

Transceiver Verification of a 20nm Altera FPGA Device
by Daniel Payne on 09-11-2014 at 6:00 pm

FPGA devices are a great way to drive silicon technology development because they contain both digital and analog IP, along with sophisticated IO cells. The highest performance IOs are transceivers, and Altera has recently designed the Arria 10 device family to include up to 96 transceivers, using a 20nm technology that can achieve… Read More


Automatic RTL Restructuring: A Need Rather Than Convenience

Automatic RTL Restructuring: A Need Rather Than Convenience
by Pawan Fangaria on 08-22-2014 at 5:00 pm

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


Another debug view in the UVM Toolbox

Another debug view in the UVM Toolbox
by Don Dingee on 08-17-2014 at 1:00 am

One of the biggest endearing qualities of a debug environment for any type of coding is availability of multiple ways to accomplish a task. Whether the preference is keyboard shortcuts, mouse left-click drill-down and right-click pull-down menus, source code view, hierarchical class view, or graphical relationship view, … Read More


Transaction-based Emulation

Transaction-based Emulation
by Paul McLellan on 08-14-2014 at 7:01 am

Verification has been going through a lot of changes in the last couple of years. Three technologies that used to be largely contained in their own silos have come together: simulation, emulation and virtual-platforms.

Until recently, the workhorse verification tool was simulation. Emulation had its place but limits on capacity… Read More


Then, Python walked in for verification

Then, Python walked in for verification
by Don Dingee on 07-31-2014 at 12:00 am

Go ahead – type “open source” into the SemiWiki search box. Lots of recent articles on the IoT, not so many on EDA tools. Change takes a while. It has only been about five years since the Big Three plus Aldec sat down at the same table to work on UVM. Since then, Aldec has also gotten behind OS-VVM, and is now linked to a relatively new open… Read More


Pizza con Questa

Pizza con Questa
by Paul McLellan on 07-30-2014 at 11:01 am

Last week I went to a lunch and learn at Mentor about their Questa formal product given by Kurt Takara. Like everyone else these days, Questa is packaged as a number of Apps for doing different tasks. Formal verification is different from other EDA tools in that different approaches can be used for different sub-tasks. There are three… Read More


Enterprise IP Management – A Whole New Gamut in Semiconductor Space

Enterprise IP Management – A Whole New Gamut in Semiconductor Space
by Pawan Fangaria on 07-29-2014 at 8:00 pm

The world of IPs in the semiconductor landscape has completely changed the semiconductor design scenario, specifically the fabless design space. Today IPs are key components of any large semiconductor design, in the same way as auto ancillaries in auto design. It’s just the beginning, in the days to come we will see SoCs just as… Read More
