Record #1253 Product Family: Software Product Line: ViewLogic Product Part: viewdraw Product Version: 7.5 Problem Title: Viewlogic: How do I LOC an IPAD4/8/16 or an OPAD4/8/16 ? Problem Description: There is no way to schematically LOC an IPAD4/8/16 or OPAD4/8/16 symbol directly. The user does have a workaround, though. Solution 1: 1) The best solution is to use a constraints file to LOC the pins, and not try to do it schematically. Refer to the Libraries Guide for proper syntax. 2) Use LogiBLOX (or XBLOX) INPUTS or OUTPUTS instead. You can attach multiple LOC attributes to these symbols, i.e. LOC[1]=P10, LOC[2]=P6, .... 3) Copy the IPADx/OPADx symbol and schematic to a user directory, and add LOCs to the individual underlying IPADs.     In the following procedure, I will use an IBUF4 as an example.     ProCapture Methodology:      a) File->Open-> Symbol IBUF4.1      b) File->Save As.. ->"Design Name PRIMARY:IBUF4.1"         ----change the XC3000/4000/5200 etc. reference to PRIMARY      c) File->Open-> Schematic IBUF4.1      d) File->Save As.. ->"Design Name PRIMARY:IBUF4.1"      e) attach LOC attributes in IBUF4.1 schematic to IPADs      f) File->Save      e) You may now use the symbol in schematic Note: If you use several IBUF4 's, then you will also need to give each of them a different name (other that IBUF4). Because of the pin location constraints, these custom macros can only be called once. End of Record #1253 - Last Modified: 04/03/98 12:26
