Many tools find clock domain crossings (CDCs) in FPGA designs. Some don’t find the right ones since they don’t comprehend things like in-house synchronizer constructs. Some find too many based on misunderstanding intent, inaccurate constraints, and other factors that lead to noise.… Read More
A few weeks ago we previewed a Synopsys webinar describing how they are linking the ARM Juno Development Platform with the HAPS-80 and HAPS ProtoCompiler environment. I’ve had a look at the archived event and have some additional thoughts.… Read More
Both Altera and Xilinx are innovative companies with robust ecosystems, right? It would be a terrible shame if you located the perfect FPGA IP block for a design, but couldn’t use it because it was in the “wrong” format for your preferred FPGA. What if there were a way around that?
There is a compelling argument to use each FPGA vendor’s… Read More
The prototype is obviously the end goal of FPGA-based prototyping, however success of the journey relies on how quickly defects can be found and rectified. Winning in the debug phase involves a combination of methodology, capability, and planning. Synopsys recently aired a webinar on their HAPS environment and its debug ecosystem.… Read More
For the latest incremental improvements to its Riviera-PRO functional verification platform, Aldec has turned to streamlining random constraint performance. The new Riviera-PRO 2016.02 release also is now fully supported on Windows 10 and adds a new debugger tool.… Read More
Verifying chip designs has always suffered from a two-pronged problem. The first problem is that actually building silicon is too expensive and too slow to use as a verification tool (when it happens, it is not a good thing and is called a “re-spin”). The second problem is that simulation is, and has always been, too slow.
When Xilinx… Read More
I wrote back in March about Undo Software. They have a reverse debugging solution called UndoDB (the DB is for debug, not database). I have a soft spot for reverse debugging ever since seeing one of the engineers at Virtutech type reverse single step and seeing the code back up a single instruction and realizing that literally months… Read More
When I was a Virtutech a few years ago we had a product called Hindsight. It looked close to magic when you used it since it allowed you to run code backwards. I assume that the technology is still lurking under the hood in Wind River’s Simics product, now part of Intel. The way the code worked is that as the software executed, Simics… Read More
