From 9dec5f5f1ef7dcb0f7e02cff53642b4eb00c4900 Mon Sep 17 00:00:00 2001 From: Holger Vogt Date: Sat, 2 Feb 2019 09:38:57 +0100 Subject: [PATCH] An example for non-convergence of the pll if the stepszelimit is removed. Adding a somewhat relaxed limit by TMAX in the tran command will speed up the simulation by a factor of 1.5 without compromising the result. --- examples/xspice/pll/pll-xspice-fstep.cir | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/examples/xspice/pll/pll-xspice-fstep.cir b/examples/xspice/pll/pll-xspice-fstep.cir index 5c79e1522..4f86fe9d9 100644 --- a/examples/xspice/pll/pll-xspice-fstep.cir +++ b/examples/xspice/pll/pll-xspice-fstep.cir @@ -80,7 +80,7 @@ let pw2 = per2/2 let per3=1/f3 let pw3 = per3/2 *simulate -tran 0.1n $&simtime uic +tran 0.1n $&simtime 0 0.5n uic *change frequency after stopping * first pair of [] without spaces, second pair with spaces alter @vref[pulse] = [ 0 3.3 10n 1n 1n $&pw2 $&per2 ]
