Techniques are provided for determining consequences of an injected fault on a system running a given application program or operating system, in order to measure the software impact of a hardware soft error on the application program / operating system. The application program software is emulated instruction-by-instruction, where source operands are randomly modified before an instruction is executed, and destination operands are randomly modified after an instruction is executed, in order to mimic hardware soft errors. In addition, a program counter is randomly modified after execution of a branch instruction. The resulting consequences of such modifications are monitored such that a fault of an instruction being executed is modeled in order to determine a soft error rate (SER) for a software application program or operating system.

A smart memory system preferably includes a memory including one or more memory chips, and a processor including one or more memory processor chips. The system may include a smart memory controller capable of performing a bit error rate built-in self test. The smart memory control may include bit error rate controller logic configured to control the bit error rate built-in self test. A write error rate test pattern generator may generate a write error test pattern for the bit error rate built-in self test. A read error rate test pattern generator may generate a read error test pattern for the built-in self test. The smart memory controller may internally generate an error rate timing pattern, perform built-in self test, measure the resulting error rate, automatically adjust one or more test parameters based on the measured error rate, and repeat the built-in self test using the adjusted parameters.

A system (50) includes a communication path (170) and transmits data on a network (103, 106). A transmitter (101) transmits data on the network and a receiver (112) receives data from the network. A component (102, 114) in the communication path has a transfer characteristic (C1, C2, C3) adjusted in response to errors in data transmitted over and received from the network in order to reduce the error rate.

The invention discloses a method for testing code error rate based on a high-speed serial interface coding mode and relates to code error rate testing technology which is provided for solving the problems that the prior code error rate testing mode can not properly test the bit error rate of a signal channel and is complex. The method comprises the following technical proposal: in decoding, the number of code sets which do not meet a coding rule is counted; and the total quantity of transmitted data is calculated so as to determine the code error rate. The invention simultaneously discloses a device for realizing the method. The method does not need to mount an external code error testing instrument; the calculated code error rate is real-time code error rate of the signal channel and directly reflects the transmission quality of the signal channel; and the tested code error rate has high reference value.

The invention discloses a construction method, a test method and a system for a safety control device RTDS dynamic model test system. The system construction method includes: creating a first custom component, generating a Connection.def file; and a C language file associated with the Connection.def file Write the first function code to generate the main wiring model that meets the requirements of the security device RTDS dynamic model test environment through parameter settings; create the second custom component and generate the Protection.def file; the C language file associated with the Protection.def file Write the free combination of switch opening and closing under a specific delay through parameter setting to realize the second function code for simulating the action of the relay protection device; implant the Connection.def file and Protection.def file into the public component library of RTDS, Get the Connection element and Protection element. Integrating the functions of the relay protection device used for dynamic model testing with safety control devices into the simulation model reduces the workload of testers, improves the versatility of the simulation model, and reduces the test error rate.
