誰能把ppc上得 nspice改到 palm pda

有 source code 又沒有 高手把他 轉成 treo650 arm base tools ... 都是 arm base xscal cpu 應該可能吧InstallationTo install NGSpice-PPC simply copy the "ng" directory contained in the zip file to the root directory of your device. If you want to have a link in the Start Menu: in the [i]"file explorer"[/i], create a link to [i]NGSpice.exe[/i] and copy it to [i]"/windows/start menu" [/i](or [i]startmen? in the german version)
SimulationUse your favorite text editor and write the circuit description.
Personally I'm using [url=http://www.rainer-keuchel.de/wince/vim.html][color=#0000ff]Rainer Keuchel's VIM port[/color][/url] as it supports syntax highlighting for spice circuit files. But every other text editor able to save raw ascii text can be used.
Start [i]ngspice.exe[/i] by clicking on it. (Or on a link, if you made one.)
The program shows 3 textfields. The upper field shows the simulator's answers, the bottom right field shows the status and the bottom left field is the command prompt.
Simulation can now be controlled with the same commands you would use on your desktop machine. (e.g. rc3.cir [i][enter][/i] run [i][enter][/i] plot v(3) [i][enter][/i])
A new graph window will appear after each plot command.
The window can be closed by clicking on the [i]"X"[/i] in it's titlebar. When clicking a little bit left to the [i]"X"[/i], it can be toggled to fullscreen mode. The window can also be moved around by clicking and dragging the titlebar. It can be resized by dragging the thin frame which surrounds it.
A Task-Switcher like Harald-René's [url=http://www.hfrmobile.com/app_Switch_T1/index.htm][color=#0000ff]switch[/color][/url] is very usefull at this point to change between different graphs, the simulator and the editor.
