I meet a problem in discrete events

[yanshuchang]

function switch(;name)

    @named   p   =  Pin()
    @named   n   =  Pin()

    #@parameters sig = m
    
    sts = @variables begin
        v(t) 
        i(t) 
    end    


    sc = [10] => [i ~ 0]

    eqs = [v ~ p.v - n.v
           0 ~ p.i + n.i
           i ~ p.i]
   
    injection = (t == 10) => [i ~ 0]
           
    modelll=compose(ODESystem(eqs, t, sts, []; name=name), p, n)
    
    @named modelf = ODESystem(modelll, t, [], []; discrete_events = injection)
    
    return modelf

end


@named     igbt1 = switch()

I got such error, why?

Your syntax is wrong.

           @named   p   =  Pin()
           @named   n   =  Pin()

           #@parameters sig = m

           sts = @variables begin
               v(t)

           end
