Thus, it is possible to form a structural hierarchy of source documents, which can be simple or complex, depending on the need for the task. On the other hand, a sub-schema may also contain further sheet symbols that refer to lower-level schematic sheets or IIDL files. The name of each sheet symbol refers to the underlying schematic file (or HDL file) that it represents graphically. Each of the source documents that define the project is represented on the top sheet with a sheet symbol. The sheet structure itself is formed using special symbols called the schematic sheet symbol. At the head of this structure is the single master sheet of the schematic, more commonly referred to as the top sheet of the design. Logical Blocks in Schematic AltiumĪ multi-sheet project is formed as a hierarchical structure of logical blocks, where each block can be either a schematic sheet or an HDL file (VHDL or Verilog).
More details about "rooms" and their properties will be discussed in another article. Rooms are formed according to the sheets of the scheme, and it is most advisable to use rooms in cases where when there are repeating fragments of the circuit since by tracing in one “room” it can be duplicated in the rest. When transferring information from a schematic to a board, Altium Designer automatically generates rooms on the board, unless this is disabled in the settings.
"Rooms" - areas of the board, to which certain groups of components are assigned. Updating PCB from Schematic AltiumĪ big role here is played by the so-called.
Given the low efficiency of automatic placement, the article will consider only manual and semi-automatic placement tools, which include the tools of the Tools > ComponentPlacement group. While AltiumDesigner has automatic and semi-automated board placement tools, any experienced designer knows that no software can place components on a board better than a human. Therefore, issues related to the parallel operation of the circuit - the board will also be considered. At this stage of pcb board design, it is necessary to transfer data from the schematic editor to the board editor, the location of components, taking into account the technical specifications and the formation of the topology of printed conductors.
