The flexibility of RISC-V processor IP allows much freedom to meet specific requirements – but it also opens the potential for many bugs created during the design process. Advanced processor features are especially prone to errors, increasing the difficulty and time needed for thorough verification. Born out of necessity, … Read More
A UVM testbench is a large and complex piece of software. At some stage, like any other large and complex piece of software, a verification environment written using UVM is going to require debugging.
There are various debugging features built into UVM to help with this. In this webinar Doulos Senior Member Technical Staff, Doug… Read More
Success with Open-Source Formal Verification
The dream of 100% confidence is compelling for silicon engineers. We all want that big red button to push that magically finds all of our bugs for us. Verification, after all, accounts for roughly two-thirds of logic design effort. Without that button, we have to create reference models,… Read More
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
Our previous Blue Pearl post looked at the breadth of contextual visualization capability in the GUI to speed up debug. Two other important aspects of the ASIC & FPGA pre-synthesis workflow are automating analysis with scripts and managing the stream of messages produced. Let’s look at these aspects… Read More
