From version 2.4 XJDeveloper and XJRunner support logic devices. A library of definitions for common logic devices is shipped with XJDeveloper. This post details this feature.
The library consists of definitions for the common devices in the 7400 series of logic that XJTAG can support (devices with no state). It also contains definitions for some other devices that we have seen used on customers’ boards. When a device is categorised in XJDeveloper the definitions in the library are always available to use.
If you find a definition that is not in the library, and you feel it should be, contact XJTAG Support and we may include it in a future release. Improving and updating the library is a continuous process with any changes included in the next release of the software.
The library has been designed to make using any updated definitions as simple as possible. When a project is opened XJDeveloper checks to see whether there are newer definitions of the logic used in the project and if there are it prompts to see if you want to use the updated definitions.
Hello,
I am missing Bus Transceivers in the library. For example 74LVC1T45, 74LVC8T245.
kind regards
Paul
Hi Paul,
both of those devices are present in the library. If you try to assign a device as logic then in the ‘search name’ box type 1T45 or 8T245 or indeed the full string 74LVC1T45 etc then it should show you the device and allow you to select a footprint (there are 6 available footprints for the 1T45 and 3 for the 8T245.
I hope that helps,
Bob
hi stuart,
is there any library for capacitors and diodes
why library not covering diode and capacitors? how to test those?
please explain it
We don’t really regard a diode as a logic device, and since it can be represented in more than one way (depending which pin you think is the ‘output’) we haven’t put it in the library. Sure, you can represent one with a truth-table if you like – in which case you can create a truth table yourself (on the Logic Files screen in XJDeveloper) to suit your needs.
As for a capacitor – that’s not a logic (or even a digital) device, so it is not in the logic library. If your JTAG devices support 1149.6, XJTAG performs automatic testing of coupling capacitors (define them as Passive Devices) during the connection test. Otherwise, testing of capacitors is limited. Please contact XJTAG Support directly if you require more information about this.
Thanks,
Bob
