Case Study: Testing of IP-based Mixed-Signal Fax/Modem System-on-Chip
نویسندگان
چکیده
Several test methods are applied for highly integrated mixed-signal Fax/Modem system-on-chip which consists of heterogeneous modules: MCU, DSP, PLA, memories, and CODEC. Top-level separate module testing is devised by test management unit which configures several IP-based module testing. External test programs are down-loaded on the embedded RAM and executed to evaluate the function of DSP in real-time which have 98.2% fault coverage. Built-in self-test program is generated to test ROM and RAM. Individually accessible paths are designed for separate testing of each transmit and receive block in CODEC. Overall test logic has 1.2% additional chip area.

A Fully Integrated Range-Finder Based on the Line-Stripe Method
In this paper, an imaging chip for acquiring range information using by 0.35 μm CMOS technology and 5V power supply has been described. The system can extract range information without any mechanical movement and all the signal processing is done on the chip. All of the image sensors and mixed-signal processors are integrated in the chip. The design range is 1.5m-10m with 18 scales.
متن کاملTest Strategies for Embedded ADC Cores in a System-on-Chip, A Case Study
Testing of a deeply embedded mixed-signal core in a System-on-Chip (SoC) is a challenging issue due to the communication bottleneck in accessing the core from external automatic test equipment. Consequently, in many cases the preferred approach is built-in self-test (BIST), where the major part of test activity is performed within the unit-under-test and only final results are communicated to t...

An on-chip analog mixed-signal testing, compliant with IEEE 1149.4 standard is presented. The testing technique is based on sinusoidal output response characterizations, yielding a complete detection of AC and DC fault signatures without a need for simulation-before-test process. The testing system is an extension of IEEE 1149.4 standard, and affords functionalities for both pre-screening on-ch...
