spectre says "The following branches form a loop of rigid branches "

eashwar g

there is no connection to the particular node...which spectre is listing . i dont know why it keeps pointing out the error . please check this

Fatal error found by spectre during topology check.
    FATAL: The following branches form a loop of rigid branches (shorts) when added to the circuit:
        I16:w_position_flow (from state to 0)

but as per my circuit that connection is must .. so suggest possible solution

  • if we have a transistor with pins g,d,s 1) if i connect a voltage source to pin g and plot vi char 2)similarly in same schematic i create another transistor with same pins g,d,s and plot vi char will there be any issues 3)the problem is the component i created is in veriloga so for a current it would be I(p,n) if i have to change pin names then i have to modify whole code 4)this is the problem i am facing
