Multi-Sheet Designs and Connectivity
It is increasingly common in larger designs to split the schematic into multiple sheets. This
serves both to reduce clutter on the schematic and also to organize the design into logical
blocks. Proteus fully supports this methodology and we have arranged our tutorial design into
two sheets in order to cover the relevant procedures. The work we have done so far has been
to complete the first sheet (processor, sensors and memory circuitry), meaning we still need to
cover the analog and power circuitry. We’ll do this on a separate sheet.
While beyond the scope of this tutorial it is worth mentioning that Project Clips provide a method
for re-using logical blocks of design and layout. More detail is in the reference manual and a
short tutorial movie is linked on our website.
Also, note that what we are doing here is adding a second sheet at the same level as the first
sheet. Proteus fully supports hierarchical designs where you use sub-circuits to contain logical
blocks. This is discussed in detail in the reference manual.
Adding Sheets to a Design
To add a new sheet to the schematic we simply invoke the command from the Design menu as
shown below.
