In Virtuoso, I'm using the "vpulse" from the analoglib, with basic characteristics, "voltage 1: 0V, voltage 2: 1.2V, period: 1ns, delay time: 10ps, rise time: 50ps". Then I use ADE to check if this voltage pulse works. If I use Spectre as the simulator, the signal comes out as a normal periodic pulse wave. However, if I chose Hspice(using NCSU freepdk 45nm) as the simulator using the same conditions, it gets a weird straight line output. Can anyone help? Thanks!
