2372 - LatticeECP3:  Can the bitstream used for the regular device be programmed in the low power device of LatticeECP3?  

2372 - LatticeECP3:  Can the bitstream used for the regular device be programmed in the low power device of LatticeECP3?  

Yes.  The bit stream formats are the same for the regular LatticeECP3 and the low power LatticeECP3 devices. For example, LFE3-70EA-8TN1156C and the low power version "LFE3-70EA-8LTN1156C" can use the same bitstream file.  There is no need to generate another bitstream file for the low power version device.
