我是对RAM做re-ch，当做到configure时失败，原因为生成的inst文件中add_pin mem_int default -internal -spice_node [get_config_opt mem_int_node]
mem_int_node不知如何查找？看了user guide，还是没弄明白。
user guide中写了4个步骤：
1. Write the instance file for the memory with the state-table describing the
simplest write, read and idle/disabled function of the memory.
(state-table我已经加了)
2. Make sure that the state-table is correct. This can be done by configuring
and characterizing a delay arc from CLK to output. If the delay arc is
characterized successfully, it means that the functional description is
correct.
（state-table确认是正确的。）
3. Then, the internal node mem_int should be defined in the instance file as
follows:
Example 215
add_pin mem_int default –internal –spice_node
[get_config_opt mem_int_node]
（inst文件中有这一行）
4. Set the target_bits parameter of the pin type corresponding to the data
bus to 0 in configure.tcl.
（configure.tcl中有设为0）
Once this preliminary setup is done, you can then find the internal nodes using
a set of commands. Once the internal SPICE node is located, substitute the
SPICE node name in the following command in the instance file:
Example 216
add_pin mem_int default –internal –spice_node
{actual_internal_spice_node}
关键就是在上面红色字体部分，这个地方说的，using a set of commands，到底用的是什么命令啊？ |
