ScanWorks® Processor-based Functional Test for NXP - i.MX Application Processors
■ASSET’s ScanWorks® Processor-based Functional Test (PFT) product supports the NXP i.MX6 Application Processor family. The i.MX 6 series of applications processors com bines scalable platforms with broad levels of integration and power-efficient processing capabilities particularly suited to multimedia applications.
■The ASSET ScanWorks PFT provides functional board testing of buses and devices, other than DDR, to identify at-speed faults not found in structural test.This new functional test IP is integrated with the best-in-class ScanWorks test platform. PFT provides high test coverage for all devices with at-speed functionality. Combining PFT with ScanWorks PFTDDR delivers greater test coverage to meet design quality requirements of today’s high speed designs. ScanWorks tools are designed to maximize production efficiency and simplify the test development life-cycle.
■PFT (Figure 1) uses a tar-get agent to configure the interface between SoC embedded controller the and the bus endpoints. The agents are installed in internal RAM within the SoC and provide task specific actions: testing for device existence and device verification. The in-target agent tasks ensure maximum testing speeds and accurate device control.
■The ScanWorks design environment provides for the control and management of test project resources. Once the resources are configured, (eg. TCK setting correct, JTAG controller selection, etc.) the action development is intuitive to create a test action. After all test actions are interactively verified, ScanWorks supports rapid transition from development to deployment ensuring consistency regardless of where the project is deployed. This reuse of ScanWorks projects eliminates costly communications mistakes.
