Hey, it’s not too late to attend SNUG Silicon Valley: http://www.synopsys.com/Community/SNUG/Silicon%20Valley/pages/default.aspx

Design defects (bugs) can be introduced at multiple levels in the design process from RTL defects, SW defects and Integration defects. The key to rapidly locating these bugs is to tailor the debug strategy to the type of bugs you are looking for. Depending on where you are in the design cycle usually dictates which type of bug is more prevalent. Physical Prototyping exercises the RTL, SW and the fully integrated design so is a key technology for design verification. Having the right debug tool set if critical to accelerate the verification task.
Great article by Tom De Schutter on using Physical Prototyping for software development. The article goes into other use cases and explores the age old make vs. buy decision making process.

In a continuation of last week’s blog titled “Validating USB Type-C using Physical Prototyping” one of the key USB folks here at Synopsys, Morten Christiansen, made a short 30 second video of the DesignWare USB Type-C physical prototype in action. (Click the picture to take you to the video)
This week Synopsys Introduced the DesignWare USB 3.1 Type-C IP with DisplayPort 1.3 and HDCP 2.2 for High-Bandwidth Data Transfer with Content Protection. USB has been continually evolving and USB Type-C is the one cable to connect them all. The USB Type-C is already gaining widespread acceptance and is becoming the most rapidly adopted USB standard in history. The need to rapidly adopt a new standard comes with challenges for the design engineers, verification team and the software developers.

Regardless of the market segment your product targets you are being required to build it with the lowest power operation to either compete, differentiate or just be more green. This week I ran into a customer who unfortunately had to re-spin their chip due to a low power mode of operation issue. The software was able to put the chip into a low power mode but due to a bug, they were unable to get the chip out of the low power mode cleanly without a system reset. This customer wanted to better verify the low power modes before tape-out this time around.
Back in 2011 I had a vision, a vision for how users of both IP and FPGA-Based Prototypes could be more productive. The problems these users faced was not to do with bugs or lack of capabilities in the products but from the fact that the usage crossed between the two products. IP users traditionally are not experienced prototypers and prototypers lacked IP specific knowledge. Of course this was not helped by the fact that the IP did not document it’s prototyping specific needs. For example, the IP is optimized for ASIC deployment and when you prototype it the clocking, reset and rams sometimes need to be modified to fit into a FPGA environment. Another issue is that as it’s ASIC IP not all configurations can be physically supported in FPGA. For example while the IP might support up to 16 IO ports on the prototype you might only be physically implement up to 4.
I ran across this blog on Imaginations website which covers details on prototyping the PowerVR Series6XT on HAPS: http://blog.imgtec.com/powervr/prototyping-a-powervr-series6xt-gpu-using-an-optimized-flow-from-synopsys
