LLCR Pin Socket Testing with the MODEL 3732 High Density Matrix Card Computer processors (CPUs) today have come a long way from the computer processors of the past. They draw more power, run at lower voltages, and have more pins than ever before.

This application note describes how to decode standard DTMF tones using the minimum number of external discrete components and a PIC. The two examples use a PIC which has an 8 bit timer and either a comparator or an ADC, although it can be modified for use on a PIC which has only digital I/O. The Appendices have example code for the 16C662 (with comparator) and 16F877 (using the ADC). As the majority of the Digital Signal Processing is done in software, little is required in the way of external signal conditioning. Software techniques are used to MODEL the individual elements of a DTMF Decoder IC.

IBIS 模型在做类似板级SI 仿真得到广泛应用。在做仿真的初级阶段,经常对于ibis 模型的描述有些疑问,只知道把模型拿来转换为软件所支持的格式或者直接使用,而对于IBIS 模型里面的数据描述什么都不算很明白,因此下面的一些描述是整理出来的一点对于ibis 的基本理解。在此引用很多presention来描述ibis 内容(有的照抄过来,阿弥陀佛,不要说抄袭,只不过习惯信手拈来说明一些问题),仅此向如muranyi 等ibis 先驱者致敬。本文难免有些错误或者考虑不周,随时欢迎进行讨论并对其进行修改!IBIS 模型的一些基本概念IBIS 这个词是Input/Output buffer information specification 的缩写。本文是基于IBIS ver3.2 所撰写出来(www.eigroup.org/IBIS/可下载到各种版本spec),ver4.2增加很多新特性,由于在目前设计中没用到不予以讨论。。。在业界经常会把spice 模型描述为transistor MODEL 是因为它描述很多电路细节问题。而把ibis 模型描述为behavioral MODEL 是因为它并不象spice 模型那样描述电路的构成,IBIS 模型描述的只不过是电路的一种外在表现,象个黑匣子一样,输入什么然后就得到输出结果,而不需要了解里面驱动或者接收的电路构成。因此有所谓的garbage in, garbage out,ibis 模型的仿真精度依赖于模型的准确度以及考虑的worse case,因此无论你的模型如何精确而考虑的worse case 不周全或者你考虑的worse case 如何周全而模型不精确,都是得不到较好的仿真精度。

IP核生成文件:(Xilinx/Altera 同) IP核生成器生成 ip 后有两个文件对我们比较有用,假设生成了一个 asyn_fifo 的核,则asyn_fifo.veo 给出了例化该核方式(或者在 Edit-》Language Template-》COREGEN 中找到verilog/VHDL 的例化方式)。asyn_fifo.v 是该核的行为模型,主要调用了 xilinx 行为模型库的模块,仿真时该文件也要加入工程。(在 ISE中点中该核,在对应的 processes 窗口中运行“ View Verilog Functional MODEL ”即可查看该 .v 文件)。如下图所示。
