AR# 45464: PlanAhead - Bank constraints are not supported in PlanAhead
PlanAhead - Bank constraints are not supported in PlanAhead
I amconverting an ISE design toPlanAhead tool.My ISEconstraints file LOCed pins using bank constraints. PlanAhead tool neither tells me if a pin has a bank constraint nor lets me set a bank constraint (like PACE did). How do I fix this?
# I/O INST "Data_Ctl*" LOC = "Bank11"; INST "Data*" LOC = "Bank11"; INST "Clk*" LOC = "Bank11";
PlanAhead tool does not support Bank constraints.
In PlanAhead tool, ports need to beLOCed it to specific site.
Note: The Bank constraint support in ISE softwaredid not take timing or optimal placement into consideration. It would only look for the first available legal site.
