No single factor affects the quality of your PCBA design process more than the EDA tool you use. Therefore, it is important to do a PCB CAD software comparison that weighs the benefits versus the cost to ensure your design program meets your requirements today and tomorrow.
Comparing the Best PCB CAD Software
The table below lists a compilation of the top PCBA design programs, each of which is quite capable of meeting the basic requirements for designing a circuit board. For this PCB CAD software comparison, the programs are ranked according to an overall rating on a 0-100 percentage scale calculated from a weighted sum of benefits and cost factors.
The cost, which directly contributes 30% to the overall score, is an inclusive quantitative measure of pricing for the most comprehensive version of the program on a 0 to 100-point scale (the higher the cost, the lower the rating). This includes any licensing, registration, and other fees necessary to access full functionality. Advanced and custom features comprise the benefits*, which accounts for 60% of the overall rating, directly. The final 10% of the overall rating is for scalability. This factor, which adds to benefits and costs, reflects how robust the PCB CAD software platform is in responding to your increasingly complex design requirements. Again, a 100-point scale is used with 0 indicating the tool does not include any inherent scalable capabilities; such as the ability to add PI, SI, thermal, or other analyses to ensure design compliance with industry standards.
*Note: No disadvantages or negative scoring are included in either rating.

Summary:
DipTrace is an easy-to-learn and use PCB CAD program that includes simple component creation capability.
EasyEDA
Benefits:
Simple to use
Extensive component symbol and footprint library
Basic circuit simulation
Cost: Free
Summary:
EasyEDA includes all of the functionality needed to design circuit boards. It also includes limited simulation capability and export to other PCB CAD software program formats.
PCB CAD Software: Optimizing Efficiency and Effectiveness
As the PCB CAD software comparison above illustrates, there is significant variation in benefits and costs among the top circuit board design programs. By integrating EDA product developments and techniques, you can elevate the capabilities and usability of your CAD PCB design solution. However, there are additional product development challenges that should be considered.
A significant issue that can accompany EDA tool integration is incompatibility. For example, converting to an alternative format (such as to perform simulations) can result in a loss of design detail that translates into manufacturing errors. Component unavailability and other supply chain problems can also wreak havoc with PCBA development and production. The right professional product design software can help you overcome these obstacles and maximize the quality and efficiency of your PCBA development process.
