A method of increasing the operating reliability of high-frequency protection

The breakdown of the PDE 2003 type directed and differential-phase high-frequency protection based on integrated microcircuits for a single-phase short circuit on a 330-kV line when the protection is operating in the directed mode is considered. It is shown that separation of the exposure time in the disconnection channel into two parts increases the operating reliability of the protection for disconnection in intensive high-frequency interference. The establishment of maximum (apparatus) sensitivity of the high-frequency receiver is only possible in icy regions. Translated from élektricheskie Stantsii, No. 12, December 2008, pp. 58–61.     

A Low-Cost At-Speed BIST Architecture for Embedded Processor and SRAM Cores

We have introduced a low-cost at-speed BIST architecture that enables conventional microprocessors and DSP cores to test their functional blocks and embedded SRAMs in system-on-a-chip architectures using their existing hardware and software resources. To accommodate our proposed new test methodology, minor modifications should be applied to base processor within its test phase. That is, we modify the controller to interpret some of the instructions differently only within the initial test mode. In this paper, we have proposed a fuctional self-test methodology that is deterministic in nature. In our proposed architecture, a self test program called BIST Program is stored in an embedded ROM as a vehicle for applying tests. We first start with testing processor core using our proposed architedture. Once the testing of the processor core is completed, this core is used to test the embedded SRAMs. A test algorithm which utilizes a mixture of existing memory testing techniques and covers all important memory faults is presented in this paper. The proposed memory test algorithm covers 100% of the faults under the fault model plus a data retention test. The hardware overhead in the proposed architecture is shown to be negligible. This architecture is implemented on UTS-DSP (University of Tehran and Iran Communicaton Industries (SAMA)) IC which has been designed in VLSI Circuits and Systems Laboratory.
