Hi Weiyi, I recommend abandoning the icons in the SPICE Parts library altogether and just use SPICE Code.
Take a look at the example I have attached and see if it helps you get to where you're going. I also attached the .spi (netlist) file that I generated with Electric. I run the netlist with LTSpice (free). Good luck, Lincoln -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of war_of_justice Sent: Monday, December 28, 2009 9:37 PM To: Electric VLSI Editor Subject: Re: Electric Question Thank You Lincoin. I have tried to go to look under schematic and go under spice icon to add in the PWL source icon and labelled it (wonder whether I use the correct source for current PWL implementation) . I have also added in the VDD and VGND reference voltage. However, I am stuck in the spice code, if my PWL (0 0.01m 1u 0.01m 9u 0.05m 10u 0.05m) for LTspice, how should i write down the spice code for electric? I am still quite new to electric, hope that anyone can help with this, thanks a lot.
