I have a datapath module, after synthesize -to_generic, there are some CSA module has been added by RC, which naming is very ugly. Both in module name and instance name.
its RTL is :assign mout_int = smult(coeff,datain); where smult is a function.
its instance name is : \smult_30_22:mux_59_9_g1, I don't want "/" and ":" which is not accepted by STA tool. I can't find the option to change name. Besides re-write by design compiler, is there any option in RC I can use to replace them?
I also got ugly module name such as \csa_tree_smult_30_22:sub_62_34_group_325
thanks for the help!
Any reason you cannot use change_names to address whatever limitatios the downstream tools may have ?
In reply to grasshopper:
Thanks for the help. I did not find this command before you mentioned it.I search for lots of attributes and don't know there is a command for it.
But I am still curious if there is command/attribute such as "hdl_use_if_generate_prefix" which can constraint the tool "before" the elaboration.
In reply to tompy:

> apropo naming
should show you all attributes and commands witth such words in their names or their help strings. As per a specific attribute to control naming exclusively for functions, there is no such thing documented that I am aware of. If your STA does not support the current syntax for functions, or anything else for that mattter, why not use change_names and ensure that your output, whether from functions or anything else, is STA friendly? Seems like a more comprehensive solution to me
one more comment on naming attributes. Generally speaking, naming style use a default to increase "by name" compatibility with Formal tools (LEC, Formality, etc). The more you change the naming defaults without changing on the formal setup, the more likely you will see increases in runtime and potentially even aborts.
