The MachXO JTAG pins on the MACHXO Mini board share the same traces with some generic IOs of the MachXO device (as shown on page 4 and page 2 of the schematic). If the new design patterns have signals driving out of these pins, they could potentially ...
The PROGRAMN pin does not affect the JTAG state machine or boundary scan cells. However, the PROGRAMN pin does clear the SRAM configuration memory of the device. Because of this, a logic low signal on PROGRAMN pin at any time during JTAG ...
The way to check the MachXO configuration status through JTAG is to use the capture instruction. For the MachXO the capture instruction (which is the instruction shifting out of the instruction register) is 0x19 (if the device is blank) or 0x1D (if ...
Description: After installing Diamond, I find under "xxxx\cae_library\simulation", there not have a simulation model for XO3L SEDFA/SEDFB Primitive. Look into this, I find XO2 device also not have a simulation model for SEDFA/SEDFB Primitive. ...
Description: When observed at Reveal for CrossLink-NX using SoftJTAG, a timing error occurs. Solution: When using reveal with SEDC make sure that no distributed RAM is used for both Trace Signal Setup and Trigger Signal Setup like below:
