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 模型在做類似板級SI 仿真得到廣泛應用。在做仿真的初級階段,經常對于ibis 模型的描述有些疑問,只知道把模型拿來轉換為軟件所支持的格式或者直接使用,而對于IBIS 模型里面的數據描述什么都不算很明白,因此下面的一些描述是整理出來的一點對于ibis 的基本理解。在此引用很多presention來描述ibis 內容(有的照抄過來,阿彌陀佛,不要說抄襲,只不過習慣信手拈來說明一些問題),僅此向如muranyi 等ibis 先驅者致敬。本文難免有些錯誤或者考慮不周,隨時歡迎進行討論并對其進行修改!IBIS 模型的一些基本概念IBIS 這個詞是Input/Output buffer information specification 的縮寫。本文是基于IBIS ver3.2 所撰寫出來(www.eigroup.org/IBIS/可下載到各種版本spec),ver4.2增加很多新特性,由于在目前設計中沒用到不予以討論。。。在業界經常會把spice 模型描述為transistor moDEl 是因為它描述很多電路細節問題。而把ibis 模型描述為behavioral moDEl 是因為它并不象spice 模型那樣描述電路的構成,IBIS 模型描述的只不過是電路的一種外在表現,象個黑匣子一樣,輸入什么然后就得到輸出結果,而不需要了解里面驅動或者接收的電路構成。因此有所謂的garbage in, garbage out,ibis 模型的仿真精度依賴于模型的準確度以及考慮的worse case,因此無論你的模型如何精確而考慮的worse case 不周全或者你考慮的worse case 如何周全而模型不精確,都是得不到較好的仿真精度。

IP核生成文件:(Xilinx/Altera 同) IP核生成器生成 ip 后有兩個文件對我們比較有用,假設生成了一個 asyn_fifo 的核,則asyn_fifo.veo 給出了例化該核方式(或者在 Edit-》Language Template-》COREGEN 中找到verilog/VHDL 的例化方式)。asyn_fifo.v 是該核的行為模型,主要調用了 xilinx 行為模型庫的模塊,仿真時該文件也要加入工程。(在 ISE中點中該核,在對應的 processes 窗口中運行“ View Verilog Functional moDEl ”即可查看該 .v 文件)。如下圖所示。
