Layout design Lab using L-edit How to build a MOSFET layout using L_edit Inverter Using L-Edit

Launch L-Edit Create New File. Create new files by choosing File > New , which opens the New File dialog: Options include: File type The type of file to create. Layout produces a Tanner Database (TDB) file. Text creates an ASCII text file for normal text editing Copy TDB setup from file For Layout files, the TDB file from which to take setup information for the new file. You will be able to choose the source setup file by selecting one from the list of predefined setup files, by typing the name of the file into the text field, or by browsing. C:\L-Edit Student v7.12\ledit.tdb Under Setup -> Design The chosen technology units should be lambda It should be 1 internal unit for 1/1000 lambda The lambda value should be equal to 1 micron.
