mode的切换,独立的一个或者几个pin去做切换,一般tm0和1,pin是独立的,不会跟其他的functionmode pin去复用,pin会进行一个译码,比如00的时候是function,01是mbist,10是scan,11是其他什么mode。来通过这个区分是某一个mode。 类似多度器,mux结构会对io的输入输出port进行一个选通,比如function的时候,port进来干啥...

一般我们把时钟的源头定义为create_clock,而分频时钟则会定义为create_generated_clock。两者的主要区别在CTS步骤,generated clock并不会产生新的clock domain(时钟域),而且定义generated clock后,clock path的起点始终位于master clock,这样source latency并不会重新计算。 Virtual clock(虚拟时钟): 设计中的某个时钟实际...
添加Constraint Mode读入sdc (理论+实践+命令)》 1 设置Delay Corner 理论: Delay Corner是之前配置好的power domain、时序/SI库(create_library_set)、RC Corner(create_rc_corner)、工作条件(create_op_cond)等的组合。每个Delay Corner都需要分配一组PVT库集合、RC Corner、时序分析的模式(单一工作条件、BC-WC...
2.运行以下命令: openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt 生成.pfx 文件后,双击文件并跟着向导安装即可.确保 key 是可导出的,并且将 key 放在 Personal Certificate Store 中. 安装 OS X 签名认证 在 OS X,签名认证必须由用户运行在辅助机器上的认证代理...

It sounds interesting because each device has a time domain response which is quite complex, slow and with a pronounced frequency dependency. All musical things, when they happen to be combined the right way. Like with vari-MU, the most of the final behaviour of the comp resides in a singl...
Set_analysis_mode -analysis_Type bcwc 3. DRC,design rule check Design rule是为了保证design功能正确,而必须满足对于output pin和net的约束。包括minimum,maximum capacitance, maximum transition, maximum fanout, minimum fanout等约束。因为只有在这些指定的约束范围内,才能从library中得到可信的行为。如果超出了一...
