QX Simulator
Quantum Computing Simulation
The realization of large-scale physical quantum computers appears to be challenging, alongside the efforts to design quantum computers, significant efforts are focusing on the development of useful quantum algorithms. In the absence of a large physical quantum computer, an accurate software simulation of quantum computers on a classical computer is required to simulate the execution of those quantum algorithms and to study the behavior of a quantum computer and improve its design. Besides simulating error-free execution quantum circuits on a perfect quantum computer, the QX simulator can simulate realistic noisy execution using different error models such as the depolarizing noise. The user can activate the error model and define a physical error probability to simulate a specific target quantum computer. This error rate can be defined based on the gate fidelity and the qubit decoherence of the target platform. -

Its graphical schematic capture interface allows you to probe schematics and produce simulation results, which can be explored further through the built-in waveform viewer. The key to most circuit designs is the speed with which you can reach an understanding of your circuit, its correctness, and its limitations. LTspice outperforms many other simulation tools and enables you to iterate your designs in minimal time. Keyboard shortcuts are an alternate way to invoke one or more commands in LTspice that would otherwise only be accessible by clicking through the menu or toolbar. Our extensive collection of technical resources tackles a wide range of LTspice topics. Learn how to use transformers, add third-party models, create, work with symbols, and more.Starting Price: Free -

CircuitHawk
BQR Reliability Engineering
Today’s electronic designs are becoming increasingly complex, making it harder to detect errors that generate high costs and hundreds of work hours. Detecting these errors in advance can be instrumental in preventing these damages. Unfortunately, in many cases, these errors are discovered only in the testing phase or at the customer’s site. BQR’s CircuitHawk is a powerful and unique (patent based) design error detection and stress analysis tool for electrical circuits. CircuitHawk detects design errors during the design phase, before layout and production. This way, no schematic, connectivity or stress errors are found in the qualification tests during final verification. CircuitHawk shortens design cycles and time to market, which in turn saves a lot of money and helps bolster corporate reputation. CircuitHawk is the only tool integrating design error detection with electrical stresses, thermal, MTBF and service life prediction at the schematic level, before PCB layout and production. -

Ansys Pharos
Ansys
Pharos combines Ansys' unparalleled EM engine capacity with a proprietary high-capacity circuit simulation engine to perform coupling analysis and provide ranking of potential EM crosstalk aggressors per victim node. By highlighting the most susceptible nets, designers can focus their design decisions to manage EM crosstalk on these nets and de-risk the design process. Pharos combines unparalleled extraction engine capacity with a built-in simulation engine to perform EM analysis and provide ranking of potential EM crosstalk aggressors per victim net. This allows designers to focus on the most critical nets in the design. Increasing design complexity, along with the broad scope of magnetic field interference, makes identifying all EM crosstalk susceptible victim/aggressor net pairs a very challenging, if not impossible, task. -

NL5 Circuit Simulator
Sidelinesoft
There are plenty of circuit simulators available on the market. Just read their ads: high performance, extremely fast, industry-standard (i.e. SPICE), easy to use, highly intuitive. If you want to see if a tool is worth using, try it yourself. That's what many NL5 users already did. I hope they will share their encouraging stories soon. A few words about what should you expect from NL5. It is not one more SPICE (and not even close), nor is it a SPICE replacement. For some tasks NL5 is far superior, for others simply good, and some tasks are not for NL5 at all.Starting Price: $500 one-time payment
