(Shakes finger and sighs.)
Do no...No, no no no NO! (Shakes finger and sighs.)<br /><br />Do not do it that way.<br /><br />The symbol is a shape used to indicate a circuit element, like a resistor symbol, a transistor symbol.<br />You have 1 resistor symbol that you use many times for different physical resistors and they can be made by Rohm, Vishay or anyone else so recording this information in the "symbol" is the wrong way to do it.<br /><br />If you put the manufacturers code in the resistor symbol, and you use it for a part from rohm then use the same symbol for a part from Vishay then the vishay part will contain the Rohm information.<br /><br />See whats happening there?<br /><br /><br />You are talking about information that belongs to a "part" the part is what joins a symbol and a component together to make the parts that you have in the stores.<br /><br />The part calls for symbol xxx and component yyy and has the manuffacturers information stored in the part entry itself.<br /><br /><br />This information should be added using an attribute within the part library and it should have the usage of "part definition" so that the information is held within the part and can be accessed using the attribute editor when you look at the part entry in the symbol properties in the design. (and I say "symbol properties" because when it is in a design the symbol will actually be placed as a "part.)<br /><br />This information can also be extracted from the pcb through the component properties and the attribute editor for a quick look, to extract it for the placement program the report generator can be used with the element "Attribute Text" and choose the part attribute.<br /><br />I can see that I need to do a tutorial on how to setup attributes for a library so that they can be extracted when and where needed the correct way.<br />Might take a while to get it right though, have to dot the T's and cross the i's. :)<br /><br />If you bought CADSTAR last year, did you get any training? If so there is information on attributes on the memory stick you should have received.<br />If on maintenance then contact your support guy and ask him to explain how all this attribute stuff works.<br />Anonymoushttps://www.blogger.com/profile/16943066981453001805noreply@blogger.comtag:blogger.com,1999:blog-777163971497499699.post-45138868852645574182014-02-11T11:08:01.584+00:002014-02-11T11:08:01.584+00:00Ok so we bought Cad* last year and we are still on...Ok so we bought Cad* last year and we are still on the starting block (legacy designs in our existing CAD package are still holding us back) so I apologise in advance if I use the wrong terms, but here we go.<br />So Cad* has a "Symbol" which is matched to a unique "Component", into which do I place the in-house stock code?<br />I plan to place the manufactures code attribute and the supplier(s) code(s) attribute into the symbol and it seems to make sense to also have our in-house stock code in the "Symbol" to create a BOM (for buying/costings) before doing the PCB layout.<br />But I need to have the in-house stock code in the "Pick & Place" file for our surface mount machine to work.<br />Do I duplicate the in-house stock code attribute (error prone) or can the report generator pull attributes from both the "Component" and its matched "Symbol" to produce the "Pick & Place" file?Smelterhttps://www.blogger.com/profile/17786874238792705729noreply@blogger.com
