Technical Field

The invention belongs to the technical field of hardware structure design and electrical design, and particularly relates to a data cooperation method based on CATIA and Cadence.

Background

In the hardware research and development design process, the electrical design and the structural design are closely related, and multiple times of cooperative work and repeated design iteration are required in the whole design process. At present, the data formats of the design tools of the two parties are different, and the data transmission of the design tools uses various other data formats; the situation that individual designers have different self-defined names for the same content exists, so that interaction becomes complicated, and both interaction parties need much manual intervention; this interaction is established between electrical and structural individual designers, and if personnel change, the interaction cannot be effectively continued. The whole interaction is complicated, the efficiency is low, and errors are easy to occur.

The CATIA's own CBD module may define forbidden layout areas, height-limited areas, etc., but all areas exist in solid geometry, and are not virtual, expressing only design constraints. The layout forbidden area and the height-limited area defined by the entity geometric body cause great interference to simulation results of assembly interference inspection, heat dissipation and the like in the structural design, and cannot be avoided. CBD modules cannot maintain the continuity of the structural design while completing the quick design interaction.
