How to modify SIG_NAME and LOCATION in backend text file

Ronnie,

Manually modifying these files under project folder is not recommended.

If you want to change refdes on schematic. Lets say for all diodes for which refdes prefix is D.

You can apply following commands in DEHDL command window as follows:

set next a

find $location=D*

change a

Now, it highlights one refdes on schematic, go there and click RMB > and select Editor.

It opens all refdes starting from D in text editor. Where you can change these as per your requirement and save the file and close it.

Now, save the design. you will see all refdes have been changed on schematic.

To rename sig_name: You can similar startegy for renaming/Modifying SIG_NAME also.

set next a

find SIG_NAME=*

change a

Now, it highlights signal names on schematic, go there and click RMB > and select Editor and change/modify the signal names as per your requirement and then save the file.

Hope it helps. Let me know how it goes for you.

Thanks for your sharing!

I have tried to execute the command you shared in the command window of DEHDL. Even though for sure there are components with prefix "Kxx" and SIG_NAME with prefix "IOxx", the group A is still empty as shown below. I think it means that there isn't any group member found with the predefined prefixes. 

I know there a way to change the $location and $SIG_NAME in text file instead of schematic: In the page to be modified, Copy all->Menu (Group->Include)->Menu Text Change->Right click on the schematic->Text editor. Then a text file will be opened, where all $location and $SIG_NAME can be found->replaced and saved. This way works, and is similar to the approach you shared I think, but I have to do the same procedure manually many time if I have many similar pages to modify, which is error-prone and tedious. 

So I want to write a python script(not limited for python), which can change the $location and $SIG_NAME by predefined table. All I need to do is creating the first page, running the script, and every property will be modified and updated. If the predefined table needs to be updated, I don't need to manually go through the previous process. It's more flexible in this manner.

I think there must have some methods to achieve this goal. If you know and share any, that would be very helpful for me!

Thanks again!

Best regards.
