PCI Express 3.0 – Testing 1, 2, 3…

The PCI-SIG Compliance workshop #84 is taking place December 4-7 in Milpitas, California. At the workshop, you can test your PCIe 3.0 device as part of the “official FYI testing” to see if your product passes compliance. However, “FYI” testing is “For Your Information” and not “official testing”, so even if your product passes compliance you won’t be able to list it on the PCIe 3.0 Integrator’s list because this is only FYI testing. Based on the ramp for Gen1 and Gen2, I’d expect “official testing” for Gen 3 to begin by mid next year.

Prior to the “official FYI testing”, there was pre-FYI testing. PCI-SIG uses the pre-FYI sessions to debug the test platforms, test software, procedures, and to get some feedback on early interoperability. Synopsys and our ecosystem partners (e.g.  test equipment providers, etc.) have been working together on PCIe 3.0 testing even before PCI-SIG had pre-FYI testing.  For Synopsys, all this testing ensures that our IP is robust and interoperable with other PCIe 3.0 devices. Not only does Synopsys benefit from passing these tests, but our customers benefit as well. When our customers are spending millions to fab a chip, it’s all about reducing risks and getting their products to market fast.

Since you are all probably tired from the initial Christmas shopping on Black Friday and Cyber Monday, I thought you might want to sit back, relax and enjoy some videos. At the PCI-SIG conference in Santa Clara this year, we videotaped demos using our DesignWare PCIe 3.0 digital controllers implemented on Synopsys’ HAPS 51 FPGA-based prototyping system.

The following demo showcases the high-performance PCI Express 3.0 interface operation at 8.0 GT/s. We show the performance throughput of a PC using an endpoint application designed with DesignWare IP for PCI Express 3.0 and use a LeCroy Summit T3 Protocol Analyzer to verify compliance to the PCI Express 3.0 specification.

This second demo uses an endpoint application as the design-under-test (DUT) and we execute PCI-SIG’s gold compliance tests to demonstrate how the DesignWare IP for PCI Express 3.0 is compliant to the specification.

On a sad note, I watched “The Game” on the Saturday after Thanksgiving. “The Game” is one of the oldest rivalries in college football between The University of Michigan Wolverines and that team from down south (no, I cannot mention their name). Unfortunately, Michigan lost 26 to 21. For those who have not read my bio, I am a graduate of the University of Michigan. M Go Blue! Unfortunately, red wine didn’t help me overcome the loss!
