Creating EMH compatible net information in a layout view

Sutlieff

Hi experts,

I have an extracted layout view that contains connectivity information.

The layout is flat but the instance name information has preserved the original hierarchy.

For example, instances are named xxx|yyy|zzz

Where "|" is the hierarchy delimiter

I would like to Create instances with the name xxx`yyy`zzz. (backtick. Under the Tilda~ key)

In addition, I have signal name with  the format aaa|bbb|ccc[0]

I would like to create nets with the name aaa`bbb'ccc<0>

I believe the netlist would then be EMH (Embedded Module Hierarchy) compatible if I could do this.

But I get the following when trying to rename instances:

( Original name: Logic|LvSh_sleep_n|pres[9]`M0

 Required new name: Logic'LvSh_sleep_n'pres[9]`M0.   (I was going to change "[" and "]" to "< " and ">" later BTW)

I used the dbSetAnyInstName procedure

*WARNING* (DB-220018): dbSetAnyInstName: The specified input name does not support the Logic`LvSh_sleep_n`pres[9]`M0 hierarchical path name. Use another valid name and then try again.

I got similar messages when using dbRenameNet() procedure on the nets.

Background info: net probing using an extracted view instead of the original schematic is failing because of failure to recognize nets.

Any inputs welcome.

Colin

    Hi Colin,

    Extracted views don't use EMH as far as I know (certainly extracted views for Quantus QRC don't - they use the CDBAFlat namespace to represent hierarchical names). There is very little SKILL support for EMH, but anyway I don't think it would achieve what you want. 

    Probably better to contact customer support over the original problem rather than trying to workaround it by modifying the extracted view.

    Regards,

    Andrew.
