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
