1. Only Virtex-7, Kintex-7, Virtex-6, Spartan-6 and Virtex-5 are supported. 
2. Only Map (Global Placement only) and PAR (Routing) support multi-threading.
3. Map only supports a multi-threading number up to 2. PAR supports up to 4.

Notes:

• SmartXplorer supports parallel runs, and the number of parallel runs can exceed the processor number on the machine.
   
• PlanAhead supports multiple jobs, and the number can be up to the processor number on the machine.

However, SmartXplorer and PlanAhead do not support multi-threading. 

Multi-threading can be specified for Map and PAR using a custom strategy file.
