ScanWorks® JTAG Test Development Station Bundle

Flexible Network Licensing

A Test Development Station can be licensed as a single-user or as a network station. As a network station, the features of the Test Development Station would be available to any users who have access to ScanWorks and the network license server. This makes a single Test Development Station license available to multiple users throughout the workplace or across the globe. ScanWorks supports network licensing with FLEXlm™ from Macrovision , the de facto standard for network licensing. With network licensing, you can manage your investment in JTAG (boundary scan) tools and make them available to those who need them. You can control who within your company has access to ScanWorks by identifying users and groups of users, by allowing users to “borrow” a license for use outside the network, and by automatically retrieving a license after a specified period of inactivity. You can maximize the cost effectiveness of your investment by tracking ScanWorks usage through FLEXlm reports and, if it’s necessary, purchasing discounted limited-term licenses for peak usage periods.

Multiple Scan Path Support

Although a single scan path provides the best test coverage and easiest test generation, there are many valid reasons for incorporating more than one scan path in a design. ScanWorks supports multiple scan paths through a combination of specialized hardware and software. It also provides easy and convenient methods for describing multiple scan paths in a single design.

The primary method of accessing more than one scan path is through the PCI-400 Four-Port Boundary-Scan Controller. This controller card connects to four independent scan paths and can be expanded to support as many as 24 scan paths. The user maps each scan path to a PCI-400 port and then selecting which ports will be active for each ScanWorks action. If more than one port is active, the scan paths are automatically concatenated together and treated as one scan path in the action. Describing multiple scan paths in a design is simplified by either the ScanWorks Design Wizard, which helps the user list the devices in each scan path in TDI-TDO order, or by the Scan Path Discovery tool, which examines the net list and automatically determines the devices in each scan path and their order.

An alternate method of supporting multiple scan paths is to use the Four-TAP Buffer/Pod with PCI-100 or PXI-100 controller cards. The Four-TAP Buffer/Pod connects to four independent scan paths and can be expanded to 96 scan paths with additional hardware. You select which scan paths will be active by setting static switch on the Four-Port Buffer/Pod or by manipulating ScanWorks’ Discrete IO signals. While the Four-TAP Buffer/Pod is not as convenient a solution as the PCI-400 Four-Port Boundary-Scan Controller, it does allow the PCI-100 or PXI-100 controller cards to be expanded to support multiple scan paths.
