You now have the capability to perform functional tests at your fingertip on the PCI card you designed and built. Using the PCI Diagnostica software, debugging PCI design is a snap. A PCI card or device designer needs to perform the following steps to test and validate his design,

	Bus level tests: This requires a PCI bus analyzer. With the bus analyzer one can examine the PCI signals on the PCI bus and also monitor the PCI bus transactions. In most cases, the PCI devices used on a PCI card that you build are off-the-shelf PCI devices and therefore the device manufacturers have already tested PCI signals and protocol for correctness for these devices.
	Functional tests: PCI card registers are accessed and examined for the required functionality. At this stage the card is not integrated with the system and no device driver has been developed yet. You should be able to read-write the registers or perform DMA interactively to test your design functionality. You should be be able to process interrupts on the fly. Accessing and manipulating registers under programmatic control to achieve testing of complex sequences is a necessity.
	System level Tests: At this level you have very good confidence on the functionality of your PCI device. The device drivers are written at this stage and your card is integrated with the system and software level tests could be performed.

Typically PCI developers are forced to jump from bus level tests to system level tests or start system level tests directly because of the lack of functional level testing tools. This results in increased frustration and difficulty to diagnose problems because they were not detected early on. This lack of productivity directly contributes to lost revenue and increased time to market the device.

Functional test is painless now. PCI Diagnostica empowers you. Catch your problems in an instant by performing functional tests without waiting for device drivers to work and the software to be ready. Beat your competition! Market your PCI design while your competition is still busy debugging their design. Success can not be any easier.

PCI Diagnostica can be customized with the definitions of all your device registers down to bit fields. DMA buffers can be allocated with a mouse click. Edit the DMA buffers directly. Write your functional test suites interactively. PCI Diagnostica integrates industry standard Tcl scripting language for you to author powerful complex test suites. Handle interrupts with Tcl. Change or modify the Interrupt handler as often as you need without rebooting the system. Yes, all of it comes with the ease of windows Graphical User Interface.

Requirement:

	System - Windows 95, 98 and ME.
	Minimum Memory- 32 MB.
	Minimum Disk Space- 50 MB.

To prevent this from happening you must not write into registers of any PCI devices other than your PCI card that you are testing. Additionally you have to make sure when you are initiating bus mastering by your PCI device, the write address is pointed at a buffer allocated by the PCI Diagnostica so that your device does not corrupt memory elsewhere.
