Abstract: A memory device testing apparatus transfers at high speed a fail signal from a failure analysis memory unit 100 to a memory failure remedy analysis unit 200. The failure analysis memory unit 100 has a data storage memory 110 and a compact memory 120. The data storage memory 110 is divided into at least two sub address spaces. The divided sub address spaces are assigned to the addresses in the compact memory 120. An address generation control unit reads data stored in the compact memory 120. An address generation unit 132 generates a memory address signal 143 based on a sub address signal 141 and a detail address signal 142. The detail address signal 142 is incremented by the address generation control unit 125. The data in the sub address space storing the fail signal is transferred to the memory failure remedy analysis unit 200. If the data read from the compact memory 120 does not contain failure information, the data stored in the corresponding sub address space is not transferred.

Abstract: A technique measuring accuracy of parasitic capacitance extraction defines the error in an extracted total net parasitic capacitance intended for timing analysis as a sum of the errors in the extracted values of the individual capacitance elements, with the error for each element being influenced by a weight factor. Similarly, the technique defines an error in the extracted value of a crosstalk factor for the net of interest as a difference between the errors in the extracted values of the individual capacitance elements, with the error in each element being influenced by a weight factor. For signal timing and crosstalk analyses, the weight factors allow a designer to focus calibration of the extraction tool on the capacitive element having the highest weight factor.
