Migrating Your IP
To use the IP migration flow:
1. Open your ALTDDIO_IN, ALTDDIO_OUT, ALTDDIO_BIDIR, or ALTIOBUF IP in the IP
Parameter Editor.
2. In the Currently selected device family, select Arria 10.
3. Click Finish to open the Altera GPIO IP Parameter Editor.
4. The Altera GPIO IP Parameter Editor will be configured similarly to the old settings.
5. If there are any incompatible settings between the two, select new supported settings.
6. Click Finish in the Altera GPIO IP Parameter Editor to regenerate the IP.
7. Replace your old IP core instantiation in RTL with the newly generated IP.
Note: The port names of the new IP core may not match the old ones, so simply changing the IP name in
the instantiation is not sufficient.
Resource Utilization and Performance
For details about the resource usage and performance of your design, refer to the compilation reports in
the Quartus II software.
To view the compilation reports in the Quartus II software, follow these steps:
1. On the Processing menu, click Start Compilation to run a full compilation.
2. After compiling the design, on the Processing menu, click Compilation Report.
3. In the Table of Contents browser, expand the Fitter folder by clicking the “+” icon.
4. To view the resource usage information, under Fitter, expand Resource section, and select Resource
Usage Summary.
5. To view the resource utilization information, under Fitter, expand Resource section, and select
Resource Utilization by Entity.
Note: The performance of the Altera GPIO IP core depends on the I/O constraints and clock phases.
To validate timing for Altera GPIO configuration, Altera recommends using the TimeQuest
Timing Analyzer.
