(b), like "get_pins {u_sys0_div2|div_clk_1_u_i_m2_cZ|combout}", Quartus pro would synthesis the design successfully. I would like to know how I make Quartus pro to optimize my project like fig. (b). May I have any advice about this issue, please? 0 Kudos Co...
create_clock -name {chs_clk_rx} -period 150.000MHz [get_ports {chs_clk_rx}]; *I know the -period 150.000MHz is odd but the timing analyzer accepts it. I have additional input clock pins that are also differential signals that I set, for example: create_clock -name {lvds...

50、fittingresults原因:有9个脚为空或接地或接上了电源措施:有时候定义了输出端口,但输出端直接赋0',便会被接地,赋1'接电源.如果你的设计中这些端口就是这样用的,那便可以不理会这些warningFoundpinsfunctioningasundefinedclocksand/ormemoryenables原因:是你作为时钟的PIN没有约束信息.可以对相应的PIN做一下设定就...

quartus使用timequest时序分析TimeQuest需要读入布局布线后网表才能进行.pdf,1 时序分析的基本概念 TimeQuest 需要读入布局布线后的网表才能进行时序分析。读入的网表是由以下一系列 的基本单元构成的: 1. Cells:Al 器件中的基本结构单元。LE 可以看作是 Cell。 2. Pins:
③ Resource Section(资源部分),具体包括Input Pins、Output Pins、I/O Bank Usage等信息,用于定量显示各种引脚类型和I/O组的使用。2.8.6 添加简单的时序约束条件本节将介绍.sdc文件及优先级,以及添加简单的时序约束的方法。1..sdc文件及优先级设计者必须将自己创建的.sdc 文件添加到工程中,以便在适配和时序分析...
