使用ispLEVER3.1设计一个ISA设备, 逻辑综合和仿真通过,但是fit时提示:
<Warning> F35510: Block A has a logic fanin of 47 due to preplaced or
block-restricted signals: routing capacity is 33
signals.
Partitioning时提示:
. . .
Shift to BUR_NOD_PHASE.

. . . . . . . . . . . . . . . .
<ERROR> F38007: *** Cannot find a Partition.
..... Only 54 percent of all signals are partitioned.
请问是因为Block A的扇入太大造成的吗?如何解决,谢谢！
