Guide to IC Design Software
Integrated Circuit (IC) design software refers to a collection of tools used by electronic engineers to create and test the layout, schematic, and physical representations of integrated circuits. These tools are essential in the development and production of computer chips and similar devices. The complexity and intricacy required in designing ICs necessitate the use of highly specialized software that can handle all aspects of the design process.
The process involves various stages including system-level design, logical design, circuit design, physical design, fabrication, packaging, testing and verification. Each stage requires its unique set of software designed for specific tasks.
In system-level design phase, a broad overview is created outlining what the IC should accomplish. It also includes developing an architectural description that details how different parts will interact to make a complete system operational. This may involve using high level synthesis (HLS) tools that convert algorithmic or behavioral descriptions into Register Transfer Level (RTL) representations.
The logical design phase takes this one step further by translating these rough outlines into more concrete concepts like logic gates. This is achieved by using Electronic Design Automation (EDA) software which helps automate most parts of this complex task. High-Level Synthesis (HLS), RTL synthesis tools are commonly used in this phase to convert high-level descriptions of circuits into gate-level descriptions.
In circuit-design phase, circuit simulation tools come into play which help designers analyze functionality under various conditions - transient analysis, AC analysis, etc., A popular choice among professionals is Spice which stands for Simulation Software with Integrated Circuit Emphasis.
Physical designs are created after successful circuit designs have been modeled and tested digitally. EDA tools such as place-and-route systems are used for implementing accurate placement strategies while considering parameters like power consumption and timing delay optimization.
Once physical designs are ready; photomasks for semiconductor manufacturing can be made through lithographic processes using fabrication tools such as CATS - Computer Aided Transcription System or Fractal's software suite.
Post fabrication, chips are packaged which also requires specialized packaging software. These digital tools help manage tasks such as the bonding diagram creation, wire sweep analysis and solving other complex geometrical problems.
The testing and verification phase may utilize a variety of different tools depending on the specific needs of the project. Functional verification makes sure that design behaves as expected while formal verification proves or disproves correctness of a design under all possible conditions. These tools are crucial in catching any faults early, saving time and money by avoiding costly changes to physical prototypes later on.
Moreover, keeping up with technology scaling trends like Moore's law; it is imperative for IC design tools to be updated regularly and to stay abreast with latest industry standards.
IC design software is highly specialized field requiring significant expertise not only in electronics engineering but also in computer science and mathematics. The use of these tools has revolutionized the speed and efficiency at which new IC designs can be created, drastically reducing both the cost and time it takes for products to hit the market. Thanks to these foundational technologies we have seen rapid advancements in virtually every facet of modern electronics over the last several decades.

How Much Does IC Design Software Cost?
The cost of Integrated Circuit (IC) design software can vary greatly depending on the complexity, functionality, brand, and licensing model. They can range from entirely free to several thousand dollars or even in excess of a million.
At the lower end of the pricing scale are open source IC design software such as Magic VLSI, Alliance CAD System, Electric VLSI Design System and Icarus Verilog. These open source software options are usually free to use and modify but may not present the full range of features found in commercial packages.
On top of that, there are various educational or student versions of commercial software like Cadence Virtuoso that schools or universities provide for students at a highly discounted price or sometimes even free. However, these versions typically come with restrictions on usage or design capacity.
Low-to-mid range commercial IC design tools aimed at smaller companies or individual designers can be found for several thousand dollars. Examples include Tanner EDA which provides an entire suite for analog/mixed-signal IC design starting around $5k per license/year.
High-end enterprise-grade IC design applications such as those offered by Cadence Design Systems, Mentor Graphics (now part of Siemens), Synopsys, etc., could cost tens to hundreds of thousands dollars per license annually depending upon the specific modules chosen. These solutions offer a comprehensive set of tools covering all aspects of digital, analog and mixed-signal IC designs including schematic capture, simulation (SPICE and faster-than-SPICE), physical layout editing & verification (DRC/LVS/ERC), parasitic extraction (RCX), place-and-route(P&R) system, etc.
Customized licensing options may also exist where you pay based on your requirements i.e., only paying for certain features/modules that you really need which could significantly bring down the costs. But note that when choosing this route additional costs may sneak up later if your requirements change and more functionality is needed.
In the realm of ultra-high-end IC design applications for large corporations designing state-of-the-art chips (think Intel, Apple, AMD, etc.), software can easily cost over a million dollars annually due to the extremely advanced technology nodes they operate at and the high level of complexity involved.
In all cases though, one must consider not just the direct licensing costs but also indirect costs such as learning/training time, maintenance/support fees, hardware requirements and so on. Consequently, pricing can be significantly affected by these factors. No matter what your budget is there's likely an IC design solution that fits within it.
