We’ve blogged dozens of times about UVM– Universal Verification Methodology at SemiWiki, and all of the major EDA vendors support UVM, so you may be lulled into thinking that UVM is totally adequate for top-down SoC verification. Yesterday I had a phone discussion with Frank Schirrmeister of Cadence about a new approach… Read More
Coverage is an important yet elusive metric for design verification. It often seems 90% of coverage comes with 10% of the effort, and getting the final 10% covered takes the remaining 90% of a project. Usually, it takes another tool or methodology to get at the 10% the first tool missed. With 100% closure difficult, most teams inspect… Read More
Chip deadlines and the time to achieve sufficient verification coverage run continuously in a tight loop like a dog chasing its tail. Naturally it is exciting when innovative technologies can be combined so that verification can gain an advantage. Software based design simulators have been the mainstay of verification methodologies.… Read More
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
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
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
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
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
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
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
