Hi all, i have one question that regarding the Creating the IP Peripheral and interconnection to GPIO?
i have create an IP peripheral for ADC and i create a output port (from User logic.VHD) in order to let me collect the ADC output and link it to another GPIO port !!!! May i know is that possible???
i do it like that:
1. i create a external output port from my ADC peripheral to collect the 14-bits output from ADC (this output port do not have external connection)
2. then i back to XPS and rescan the user repositories and then the output port exist
3. then i create an GPIO and in XPS i "Make New connection" in PORT tab
4. then in my ADC IP peripheral i connect the output port to the GPIO new connection
But ends up ERROR occur!!!!
ERROR:NgdBuild:76 - File "../implementation/adc_lcd_0_wrapper.ngc" cannot be merged into block "adc_lcd_0" (TYPE="adc_lcd_0_wrapper") because one or more pins on the block, including pin "ADC11<13>", were not found in the file. Please make sure that all pins on the instantiated component match pins in the lower-level design block (irrespective of case). If there are bussed pins on this block, make sure that the upper-level and lower-level netlists use the same bus-naming convention.
May i know what i doing wrong and how can i do that? My main purpose is to let the ADC output can be "read" in my SDK program.
