Introduction
PExBuilder-D251 is a completely controllable & observable PCI Express Endpoint. A separate desktop/laptop attachment is required to interface to the endpoint across its PCI port. PExBuilder-D251 consists of the PCI Express add in card and software running on Windows 2000/XP. The exerciser generates user controlled traffic and the Built-In Analyzer captures all transactions and displays them in a user-friendly interface.
