当存在全局时钟BUFG不足或者因为某些原因不想使用BUFG时,想使用其他时钟BUF如BUFH,BUFR等,可通过属性CLOCK_BUFFER_TYPE来实现。 二、CLOCK_BUFFER_TYPE 2.1 属性说明 CLOCK_BUFFER_TYPE用于指定时钟BUFFER的类型,通常未指定是,默认为BUFG,属性可直接代码中设置也可在XDC文件中使用。 使用模板:(* CLOCK_BUFFER_TYPE=V...
二、CLOCK_BUFFER_TYPE 2.1 属性说明 2.2 工程代码 2.3 结果 一、前言 在设计中,对于时钟端口驱动时钟单元时,工具会自动综合出全局时钟BUFG连接时钟源和时钟负载。当存在全局时钟BUFG不足或者因为某些原因不想使用BUFG时,想使用其他时钟BUF如BUFH,BUFR等,可通过属性CLOCK_BU...
