This is an alternate method of handling footprint pad net swaps that is
guaranteed to keep connectivity because it swaps the positon and the
length of pins such that their connections are also swapped.
Disabled by default, also has some restrictions on usage.
- Adds time and delay units
- Adds time domain tuning parameters entry and storage
- Adds pad-to-die delay property
- Adds time domain parameter interface for length / delay calculations
- Adds unit tracking for numerical constants through LIBEVAL
- Will need future work to truly propagate through binary expressions
- Adds time domain tuning to meander placers
- Adds time delay display to net inspector panel
- Modifies DRC to handle time domain constraints
The arc center is a pseudo coordinate which is calculated for drawing
purposes. This mid point is fixed unless the arc is modified which
should result in more reliable arc parity footprint library DRC testing.
Also change EDA_SHAPE::Compare() to use the arc mid point.
