The PCI Express electrical performance validation and compliance software provides you with a fast and easy way to verify and debug your PCI Express designs. The PCI Express electrical test software allows you to automatically execute PCI Express electrical tests for endpoints, root complex and new ASICs (chip level) and displays the results in a flexible report format. In addition to the measurement results, the report provides a margin analysis that shows how closely your device passed or failed each test.

The PCI Express electrical test software includes tests for verifying that your transmitter is compliant with the PCI Express 4.0 BASE specification at 16 GT/s which also includes uncorrelated jitter measurements and other tests while also offering updated PCIe 4.0 reference clock tests.

The PCI Express electrical test software utilizes the Q-domain approach (PCI Express 3.0 and 4.0 BASE specification) for 8G and 16G BASE jitter measurements and uses a Dual Dirac method for 5G jitter separation (described in the PCI Express 2.0 BASE and Card Electromechanical specifications). This ensures that your PCI Express TX measurements will have consistency with measurements made using the PCI-SIG’s standalone SigTest software.

For PCI Express 4.0 and PCI Express 3.0 measurements, the software incorporates new algorithms for calculating 16G and 8G specific BASE spec parameters including:

• TX unit interval
• Full swing TX voltage with no TxEQ
• Minimum swing during EIEOS for full swing
• TX uncorrelated total jitter
• TX uncorrelated deterministic jitter
• TX uncorrelated pulse width jitter
• TX deterministic DjDD uncorrelated pulse width jitter
• TX pseudo package loss
• De-emphasis and preshoot measurements for TXEQ presets (8G PCIe 3.0)
• TX DC common mode voltage
• TX AC common mode voltage
• TX absolute delta of DC common mode voltage

In addition to supporting PCIe 4.0 and PCIe 3.0 measurements, the PCI Express electrical performance validation and compliance software performs a wide range of legacy electrical tests as per the PCI Express 1.0a, 1.1, and 2.0 electrical specifications for new silicon, add-in cards, and motherboard systems as documented in chapter 4 of the base specification and section 4 of the Card Electromechanical specification. In addition to full swing (800 mV) testing, the software also supports testing for low-power, half-swing devices (400 mV) as per the PCI Express.

The PCI Express electrical performance validation and compliance software requires the high-speed serial data analysis software, one of the PCI-SIG approved compliance test fixtures for CEM or U.2 testing (CBB3 or CLB3 or the appropriate U.2 test fixtures), an Infiniium high performance real time oscilloscope, and at least two SMA/SMP cables or InfiniiMax active differential probes. Some of the measurements cannot be made with the PCI-SIG compliance test fixtures and may require you to build or otherwise acquire a custom test fixture. A custom fixture is typically needed when you are testing new silicon or custom ASIC.
