Altium Designeris an integrated computer-aided design (CAD) system for electronic equipment developed by the Australian company Altium. Previously, the same company developed P-CAD, which gained extraordinary popularity among Russian PCB designers. Altium Designer is a powerful system that allows you to implement electronic designs at the level of a circuit or program code, and then transfer information to an FPGA or printed circuit board. A distinctive feature of the program is the design structure and end-to-end integrity of development at different levels of design. In other words, design changes at the board level can be instantly transferred to the FPGA or circuit level and vice versa. Also, as a priority for the developers of this program, it is worth noting the integration of ECAD and MCAD systems.
