做pex时选择了calibreview格式,然后生成了一个叫做calibre的cell view。之后关于怎么做后仿从资料中找到了两种方法。
第一种是直接在这个calibre的cell view中进行,和前仿一样,只不过在ADE的Environment Options中第一栏的Switch View List前面加上一个calibre,如图: 第二种比较麻烦,要用hierarchy-editor建一个叫做config的cell view,然后设置一堆再进行仿真。 我记得用到verilog做数模混仿时才会用到config啊,这里是纯模拟电路的后仿为什么也要用config啊。想请教一下上面两种哪一种后仿方法是正确的? 您的意思是如果要把A、B、C这三种cell放在一起仿真就必须要用到config吗?(C应该是calibre吧)顺便请教一下hierarchy-editor建立的这个config具体是干嘛用的?就只是为了数模混合仿真? |

Both are correct,
but if you want cell A cell view is schematic, cell B cell view is veriloga, cell C cell view is calibreview, only config view can do this. |

for example,
"Switch view list =calibre schematic veriloga" means that priority calibre view>schematic view>veriloga view if cell A have both calibre view and schematic view , spectre simulation will use calibre view for cell A, if cell B have both schematic view and verilogA view , spectre simulation will use schematic view for cell B if cell C have only verilogA view , spectre simulation will use verilogA view for cell C If you wanna cell A is schematic view and cell B is verilogA view and cell C is verilogA view, only config view can do this. although hierachy editor's GUI interface is difficult to use for beginner. |
