Is well known, Cadence is a large EDA software, it can do almost all aspects of electronic design, including design ASIC, FPGA design and PCB design. Cadence has an absolute advantage in the simulation, schematic design, automatic placement and routing, layout design and verification and so on. Cadence tool contains many, including almost all aspects of EDA design. (The articles welfare)
Cadence allegro 16.x version already has a 3D view, although relatively simple, but pretty good in short, Cadence recent years the company continued to strengthen the ability to display three-dimensional PCB Editor can help PCB engineers to be more intuitive PCB design. Finally, the arrival of version 17.2, ushered in a new era of Cadence Allegro 3D design, 3D effects which in no way inferior 3D View AD software.
First, the preparations: allegro17.2, 3D model library
Second, the setting and display
1, we must first set the environment
1) env file settings. Path: CadenceSPB_16.6sharepcbte xtenv, open to see if there is setting set step_unsupported_prototype 1, if not, add in the file.
2) Step path model provided. Illustrated as follows:
2, the 3D model matches the provided components and the PCB
1) into the mating interface. Illustrated as follows:
2) Set Match
Were selected to be displayed 3d effect devices are matched, set the parameters to achieve the desired effect in the position shown. After setting click Save to save. Then click on Report to view the matching results. Illustrated as follows:
3, the display settings.
1) previously shown to be open to the respective layers.
PACKAGE GEOMETRY/PLACE_BOUND_TOP
PACKAGE GEOMETRY/PLACE_BOUND_BOTTOM
MANUFACTURING/STEP3D_ASSEMBLY_ENCLOSURE
2) Set 3d display viewing.
To this step, beautiful 3D to do it, is not very nice, you have to try it!
