ScanExpress JET – Xilinx Zynq All Programmable SoC Support

Xilinx Zynq All Programmable SoC Support

CPU Support Library for ScanExpress JET

Xilinx Zynq®-7000 All Programmable SoC devices combine the versatility of an FPGA with the software programmability of an ARM®-based processor core—a core that can be leveraged through the system JTAG port for functional test execution.

ScanExpress JET can utilize the integrated processing system (PS) in Xilinx Zynq-7000 devices to functionally test, verify, and program SDRAM, NOR Flash, and additional peripherals to ensure interface integrity and peripheral functionality. JET technology provides convenient system hardware verification throughout the entire product life cycle, even before boot and application code is available.

Standard and Custom Tests

  • CPU Initialization—Test basic communication and functions of the CPU.
  • SDRAM Test—Execute a full suite of at-speed SDRAM tests to identify functional faults at full CPU speed.
  • Parallel & SPI NOR Flash—Test, program, and verify NOR Flash at high speeds using a simple JTAG interface.
  • Custom Tests—The ScanExpress JET development system incudes a powerful scripting language and integrated script debugger; write your own test scripts or load compiled code right from the JET integrated development environment.

Supported Processors

The Xilinx Zynq-7000 CPU support library supports all Zynq-7000 series SoCs. Contact Corelis for additional part support information.

Applications

Test Engineers

JET is able to increase board test coverage by quickly combining boundary-scan testing with at-speed functional testing.

Design Engineers

JET assists in prototype debug before test firmware or test fixtures are available

Firmware/Software Engineers

JET is able to save coding time through automatic test and diagnostic generation.

Field Application Engineers

JET can be used to field validate a customer board or upgrade firmware on-site.

Repair Engineers

JET can identify board failures quickly reducing the repair cost per unit.

ScanExpress JET 13 Point Benefit

The JTAG Embedded Test (JET) method extends coverage beyond popular boundary-scan techniques to virtually every signal of the UUT that is accessible by on-board CPU(s). This includes most of the remaining non-scannable, analog and I/O port resources.
