It can be argued that the current free-software movement is the most important
thing happening in computing today. We are in the midst of a major shift from
all software being proprietary and closely held by individual companies to a large
body of software that can be freely acquired and used by any ...
笔记 Vivado时序约束
Synopsys' widely-used design constraints format, known as SDC, describes the "design intent" and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. SDC has been in use and evolving for more than 20 years, making it the most popular and pr ...
Mentor Creating Safe State Machines(Mentor)
 
Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptabl ...
电源技术 DN452 汽车应用的电源监视器
 
The LTC®4151 is a high side power monitor that includesa 12-bit ADC for measuring current and voltage, as wellas the voltage on an auxiliary input. Data is read throughthe widely used I2C interface. An unusual feature in thisdevice is its 7V to 80V operating range, allowing it to cove ...

测试测量 如何测试稳压器的负载瞬态响应
 
Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric devices and digitally based systemsfurnish transient loads that a voltage regulator mustservice. Ideally, regulator output is invariant during a loadtransient. In practice, some variation is encountered andbeco ...

This demo shows the BER performance of linear, decision feedback (DFE), and maximum likelihood sequence estimation (MLSE) equalizers when operating in a static channel with a deep null. The MLSE equalizer is invoked first with perfect channel knowledge, then with an imperfect, although straightforwa ...

nesc language introduction. nesC is an extension to C [2] designed to embody the structuring concepts and execution model of
TinyOS [1]. TinyOS is an event-driven operating system designed for sensor network nodes that
have very limited resources (e.g., 8K bytes of program memory, 512 bytes of RAM ...
