How Reusing Schematic Designs Can Benefit Your Next PCB design?

Printed Circuit Board (PCB) Design Schematic Capture

The word “reuse” in daily life has a positive impact and is associated with sustainability, efficiency, and resourcefulness.

In our day-to-day tasks, it can have a significant impact on us,

don’t you think?

Reusing existing work is a key factor in reducing the amount of time and effort required for any project, right.

As we venture into PCB Design Layout, the importance of PCB Schematic Capture becomes apparent.

How does schematic capture impact the PCB design layout,

The importance of schematic capture in PCB design layout cannot be overstated.

It serves as the blueprint for the entire design process, guiding engineers from concept to reality while ensuring accuracy, efficiency, and successful project outcomes.

Now, a question arises: how can we repurpose an existing schematic design?”

By understanding the way that design reuse works, you enable a greater ability to creatively smarter, more effective uses of your time.

Lets share how we done these work,

We designed the schematic capture by reusing for the pcb layout of the Driver Monitoring system used in an ADAS application.

So sit back, relax and be prepared to be amazed—it’s show time!

Lets dig in!

Front-End Electronic Design and Schematic Capture

Front-end electronic design and schematic capture involve the creation of electronic circuits and schematics using specialized software tools.

This process starts with our engineer’s design intent and involves utilizing Schematic Capture tools such as Cadence, Altium, KiCad, or Orcad to create a visual representation of the circuit.

In this stage, the schematic editor is used to place schematic symbols and connect them together to define the functionality of the circuit.

Once the schematic is complete, it can be used for simulation using tools like SPICE to verify the design before moving on to the pcb layout stage.

The netlist generated from the schematic capture process is then imported into the pcb design software to start the pcb layout. This involves placing components on the board and routing the traces to create the printed circuit board (PCB).

During the pcb layout stage, design constraints, mechanical requirements, and integration with other systems need to be taken into account.

PCB layout tools like Altium, Allegro, Eagle, or Autodesk are commonly used for this purpose.

Once the pcb layout is complete, the final design can be exported for manufacturing and prototyping.

Schematic Design Reuse with Hierarchical Schematics for PCB Layout

When it comes to schematic capture and pcb layout, utilizing hierarchical schematics can greatly improve productivity and reduce errors in our board design.

By reusing schematic sheets in a library and connecting them through nets, the designer can quickly create complex circuits.

With spice simulation and circuit simulation, we can simulate the circuit design before moving on to pcb layout. This can help identify potential issues early on and ensure a smoother pcb editor process.

A hierarchical schematic is where different areas of functionality are represented on the top sheet of the design project by block symbols.

Each block symbol is linked to a separate design that is incorporated into the master design. By selecting and opening a block symbol, you will open up its linked design.

The schematic tool will manage these different designs, including their nets and reference designators, so that there aren’t any data conflicts. The end result is that all of the linked designs are merged into the master design.

This functionality lends itself to design block reuse very well.

Take, for instance, a power supply that was created as a hierarchical schematic for an existing design.

When a new design requires that same power supply, it can simply be added as a referenced schematic. In the new design a block symbol is created that links to the existing power supply schematic.

Once the block symbol is placed, the new design will pull in an instance of the power supply schematic and synchronize the nets and references designators.

All that’s left is to connect the desired nets to the power supply block symbol ports.

How Reusing Schematic Designs Can Benefit Your Next PCB design?
