eco commands
用于在insertion添加eco逻辑进去。
不建议使用process_top_module_connections命令,这个命令是站在顶层,然后穿层次到模块里面的信号的连接,会自动开port,连接,不是一个好的tile flow。
1. create_instance
2. create_module
3. create_net
4. create_port
5. create_pin
6. create_connections
7. delete_connections
delete_connections obj_spec [-within] [-silent] 如果不带-within, 是删除ojb instance outside外部的连线, 带-within, 就是删除ojb inside内部的连线。
8. move_connections
move_connections -from obj_spec1 -to obj_spec2 [-net_name net_name] [-silent] If the object within obj_spec1 a PIN: The command moves the net connected to this pin to the pin specified in obj_spec2 and the pin in obj_spec1 is left unconnected.
9. get_dft_cell
命令 get_dft_cell clock_buffer -cell_selection_name tech_name_1 结果 {my_buff}
命令 get_dft_cell and -input 4 结果 {and_4}
get nets
get_nets [name_patterns] [‑below_instances instance_objects] [‑of_pins pin_objects | ‑of_ports port_objects | ‑of_gate_pins gate_pin_objects |‑of_pseudo_ports pseudo_port_objects] [-bundle] [‑hierarchical] [‑filter attribute_equation] [‑regexp] [‑nocase] [‑silent] get_nets [name_patterns] 获得net名为pattern的net get_nets -of_pins xxxpin 获取net跟pin相对应的net, net名与pin名名字一样 如果想获取pin 外面连线名,可用get_fanout -stop_on net
