Router configuration header file for SDM routers.

|
Possible configuration combinations:
|
|
* Wormhole (set VCN to 1)
|
|
ENABLE_EOF [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD]
|
|
* SDM (set VCN > 1 without define ENABLE_CLOS)
|
|
ENABLE_EOF [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD] [ENABLE_MRMA]
|
|
* SDM-Clos (set VCN > 1 and define ENABLE_CLOS)
|
|
ENABLE_EOF ENABLE_CLOS [ENABLE_CHANNEL_SLICING] [ENABLE_LOOKAHEAD] [ENABLE_CRRD [ENABLE_MRMA]]
|
|
|
|
The combinations not presented above are illegal, which may produce unexpected failures.
