其中xapp585中verilog源码放到uisrc/01_rtl中。 xapp585中提供的demo实现了7:1并串转换和1:7串并转换。对于SDR模式可以直接通过1个OSERDES实现并串转换,1个ISERDES实现串并转换。对于DDR模式,可以使用2个SERDES扩展到14个位宽实现。具体的下面我们以xapp585给出的demo分析。4.1XAPP585源码概述 首先看下...

.. FOR UPDATE 或LOCK IN SHARE MODE 相同数据时会等待其它事务结束后才执行,一般SELECT ... 则不受此影响。比如,我先执行上述语句,然后再次执行SELECT * FROM city WHERE city_id=1 FOR UPDATE时会被锁住。但是,当执行SELECT * FROM city WHERE city_id=1时并不会被锁住。(见下图实例) 1 2 3 4 5...
我们先回顾下正则表达式.下图: 描述像xy, xxy (B上转一圈), xyy, xxyy这样的字符串.然后可以进行字符串匹配.设计芯片都用Verilog语言而不是画门电路了.像x+y+这样的叫做regular expression. +代表重复1次或多次.考虑一条语句甚至一个程序:area = width * length; 词法分析从字符的流stream中挑出代号token流...
Verilog-A uses "generate" not "genvar". If I understand pancho_hideboo's code, he is generating an autonomous clock with a given phase but he is not muxing one of the input phases out. In my opinion, you need to check for changes of either P or IN and then select the correct ou...
