3 关于BUF,DLY,INV的Footprint的使用情况

  FAQ: How do you set buffer footprint working in FE IPO?

Follows the methods for setting footprint in FE:

1. If the .lib file being used has:
in_place_swap_mode : "match_footprint"

set, then footprint information needs to be defined for the cells in the library; else no cells will be swapped or inserted during IPO.

However, if the "in_place_swap_mode" variable is not set,  footprint information is not required. FE will set default footprint names on cells based on functionality.

2. Follows the other way to set up a footprint environment correctly.
- Dump the footprint info extracted automatically by FE with "reportFootPrint -outfile <footPrint.rpt>"
- Edit the footprint file so that buffers and delay cells belong to different footprints.
- Load the edited footprint info by "loadFootPrint -infile <footPrint.rpt>".

set rda_Input(ui_gen_footprint) {1}

 SocEncounter 6.2

  Run footprintless flow,command:

  set dbgGPSAutoCellFunction 1,

  no need  setBufFootPrint, setInvFootPrint, or setDelayFootPrint. 

 SocEncounter 7.1 default support footprintless flow

4 **ERROR: (SOCCK-643): The MinDelay in the clock tree specification file is too big.

Solution:
CTS will report this error when the MinDelay is set to a value greater than 50ns. 
This safe guard is in place to prevent huge buffer trees from being inserted. It is 
a hard coded value and cannot be changed.

5 How to fix proces Antenna?
     setNanoRouteMode -routeInsertAntennaDiode true
     # Set the following if a cell with "CLASS CORE ANTENNACELL" is not defined in 
the LEF
     #   setNanoRouteMode -routeAntennaCellName 
     # Set the following to output file(s) with a list of the diode instances 
inserted. One file is created for each diode insertion pass.
     #   setNanoRouteMode drouteAntennaEcoListFile fileName
     # To allow diode insertion on clock nets set the following
     #   setNanoRouteMode -routeInsertDiodeForClockNets true
     routeDesign

see the section "Calculating and Fixing Process Antenna" Violations in the "LEF/DEF 
Language Reference."

- For additional options on controlling process antenna fixing see the command 
"setNanoRouteMode" in the 
  "Encounter Command Reference."

- The command verifyProcessAntenna can be used to check for process antenna violations 
anytime after the design 
  is routed.
