How to clear connectivity error on special routes

vimalraj

hai


i have done a PnR for my design

i have 4 macros in my design, When i place them inside my core area and do special routing for VDD VSS nets, i find some nets are dangling and are open nets, i have also applied halo's for every blocks eventhough i find some error as shown in my attachment
so please help me to overcome this error..floorplan

  • The image you have attached looks like complete routing is done instead of just sroute. If you have issue with sroute, check you Macro LEF to see if those power/ground pins that you are trying to sroute are indeed defined as POWER/GROUND. Secondly, you need to verify that GlobalnetConnect has been applied to power/ground pin of your MACRO. For floating signal nets, you could check the netlist if there is a net connection.

  •  thank you diablo

    I Have cleared that error
