get_pins函数用于在SDC文件中选择特定的引脚(pin)。引脚是设计中的一个具体连接点,可以是逻辑单元(如触发器、缓冲器等)的输入或输出端口。在SDC约束中,使用get_pins可以精确地指定约束应用的范围,从而确保约束只作用于特定的逻辑单元或连接点。 示例: tcl set_max_transition 0.8 [get_pins u1/Q]
get_ports patterns :用于查找指定模式的端口(输入或输出)的集合 例如: get_portsscl get_cells patterns:用于查找设计中匹配指定模式的单元的集合 例如: get_cellsana_pll_instget_cellsclk_osc_re get_pins patterns:用于查找指定模式的引脚的集合 例如: get_pinsclk_osc_reg/Dget_pinsclk_osc_reg/Cget_pins...
get_pins用法 get_pins是一种用于获取指定对象(Object)的引脚(Pin)列表的命令。在电子设计和自动化(EDA)工具中,特别是在使用硬件描述语言(HDL)进行FPGA或ASIC设计时,get_pins命令是非常有用的。 使用get_pins命令,你可以获取具有特定命名约定的引脚,例如"CLOCK"、"RESET"等。通过对这些引脚进行时序约束,可以确保...
写sdc 的时候 需要get DUT 内部的pins的hierarchy. 为了得到准确的 hierarchy, 最好读入netlist 在get pin. 但得到netlist 综合时间较长。 可以基于dc 综合吐出来的dut.ddc(dut 是top module),来get hierarchy.用dc 跑synthesis 或 dc_sync_quick(uick flow只是完成elab/compile -map_only). 等dc 吐出 dut...
