why are the pins of port0 of 8051 are not toggling...where as port1,2 and 3 are toggling.. how to make them toggle..?
I have no idea what you mean so I'm guessing you do not say which '51 derivative you are using, but if it is one of the old steam driven ones you most likely are missing pullup resistors on P0
I am using oregano systems, 8051 IP core..I wrote a program to toggle port0..but while debuging bits are toggling but pins are not toggling..cant we solve this issue using simulator?
troubleshooting I/O (hardware) problems with a simulator seems kind of silly.
you need to study the hardware

Yes, it certainly does.
Happy Christmas Erik :)
