fixing design for simultanios excitation of a sequencer

[john23]

Hello,The circuit is supposed to delay the output of P12 because the PNP is opening gradually.
In previos version it worked great but i put P12 as a pulse and circuit just not working.
The Veb is totally different.Veb is supposed to be 0 and rise gradually.
But when i made P12 0-12V pulse my Veb is tottaly ruined.
How can i fix it so Veb will rise gradually from 0 till PNP is opening?
LTSPICE file is attached.
Thanks.

Hello,There was a basic flaw in my simulation because Vb started from 12V and went down.
In here our Vb start to zero So Veb is 12V and going down Thus its always open.
Is there a way to fix it?
Thanks.
