Multiple ADC0801 simulation is not working

[mprabu20]

Hi,
When I use more than one ADC0901 ICs in the circuit, simulation fails to generate interrupt. Only last placed ADC0801 IC will generate interrupt.
Please see the circuit attached. when I press WR button Interrupt on the lower ADC will generate and when I press RD button interrupt clears. But on the upper ADC nothing happens on both buttons.

Thanks

Could you please attach your "test-adc.pdsprj" project file here ? So that I can have it a look at.
Thanks.
