Make estimate_parasitics -spef_file foo.spef write to foo.spef, not foo_default.spef

[oharboe]

Description

It is surprising that the _default suffix is added to the filename.

To work around this, I have to add a mv command:

estimate_parasitics -placement -spef_file $::env(RESULTS_DIR)/4_cts.spef
exec mv $::env(RESULTS_DIR)/4_cts_default.spef $::env(RESULTS_DIR)/4_cts.spef

Suggested Solution

Write to the exact file that was specified on the command instead of writing to some other file.

If you have multiple corners then multiple files need to be written with unique names. With just one corner we can do as you suggest.
