Selecting the block and naming the new schematic
1 Click the CMOSINV block to select it.
2 From the Navigate menu, select Push.
Because the block is new, the Setup Block dialog box
appears.
3 Enter the new schematic name,
cmos.
4 Click OK.
5 Move the interface port symbols in the same way you
move other symbols:
a Click to select it.
b Drag it to the desired location.
c Release to complete the move.
Now draw the schematic for the CMOSINV block as
shown in Figure 21.
Drawing the two MOSFET devices
1 Click the Get New Part button to display the Part
Browser dialog box (see 7-245
).
2 Enter
M2N6804 in the Part text box.
3 Click Place & Close.
4 Press C+R, C+R and C+F to rotate the symbol
twice and flip it once so that the source and bulk pins
appear at the top. (To verify M1, see Figure 21 on
page 7-248.)
5 Move the part symbol to the desired location of M1
and click to place the part.

after pushing into the lower-level
schematic.
