Hi there,
I have some warnings which I would love to solve it when synyhesizing it using Leonardo Spectrum
These are the warnings
"C:/Jaz Synthesis Latest/rs232_060309/rs232_rxd.vhd",line 73: Warning, iShiftRegister is not assigned under reset; need loops to preserve its value.
"C:/Jaz Synthesis Latest/rs232_060309/rs232_rxd.vhd",line 73: Warning, iDataOut1 is not assigned under reset; need loops to preserve its value.
-- Compiling entity Rs232Txd(Rs232Txd_Arch)
"C:/Jaz Synthesis Latest/rs232_060309/rs232_txd.vhd",line 73: Warning, iTxdBuffer is not assigned under reset; need loops to preserve its value.
Info, Command 'read' finished successfully

CAn anyone tell me what does the warning is referring ?
The signals stated there is not under reset ? ~ what does that mean ?
Also, I wouldl ike to know how do we initialise initial value if the synthesize ignore any initialisation ?
