技术资料 使用SpecctraQuest仿真时序问题
通常我们在计算时许问题时，一般重点遵循以下两个条件以保证足够的Timing Margin：
1. Tflightmax + Driver(Tcomax) + Skew + Jitter + Crosstalk + Receiver(Setup)< Clock Period
2. Tflightmin + Driver(Tcomin) - Receiver(Hold) - Skew - Crosstalk > 0
其中Driver的Tco一般可以从器件的Datasheet上查到。 ...

This toolbox was designed as a teaching aid, which matlab is
particularly good for since source code is relatively legible and
simple to modify. However, it is still reasonably fast if used
with the supplied optimiser. However, if you really want to speed
things up you should consider compiling the ...
书籍 Cooperative+Communications
Cooperation is not a natural characteristic attributed to humans. The typical human horizon is focused
on short-term gains, which might be due to our instinct-driven subconscious occupying a grander
importance than we dare to admit [1]. Cooperating with other individuals or entities, however, usuall ...
技术资料 最全硬件工程师笔试试题集
1、下面是一些基本的数字电路知识问题，请简要回答之。(1) 什么是Setup 和Hold 时间？答：Setup/Hold Time 用于测试芯片对输入信号和时钟信号之间的时间要求。建立时间(Setup Time)是指触发器的时钟信号上升沿到来以前，数据能够保持稳定不变的时间。输入数据信号应提前时钟上升沿(如上升沿有效)T 时间到达芯片，这个T 就是 ...

数据结构 The Bit Array structure provides a compacted arrays of Booleans, with one bit for each Boolean value
The Bit Array structure provides a compacted arrays of Booleans, with one bit for each Boolean value. A 0 [1] bit corresponds to the Boolean value false [true], respectively. We can look at a stream of bytes as a stream of bits each byte contains 8 bits, so any n bytes hold n*8 bits. And the operat ...

VC书籍 Like many of my colleagues in this industry, I learned Windows programming from Charles Petzold s Pr
Like many of my colleagues in this industry, I learned Windows programming from Charles Petzold s Programming Windows—a classic programming text that is the bible to an entire generation of Windows programmers. When I set out to become an MFC programmer in 1994, I went shopping for an MFC equivalen ...
单片机编程 CAT25128－128Kb的SPI串行CMOS EEPRO
The CAT25128 is a 128&#8722;Kb Serial CMOS EEPROM device internally organized as 16Kx8 bits. This features a 64&#8722;byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are ...
