hello.
My name is Hanako Altera and I provide technical support for Altera® FPGA products at Macnica.
Configuration is essential for operating an FPGA, but what do you do when it fails?
The pins involved in configuration are determined by the "target device family" and the "configuration mode." These signals also have a "standard sequence," and failure to follow this sequence will result in a configuration error.
The main configuration schemes for Altera® FPGAs are as follows:
- active serial
- active parallel
- passive serial
- passive parallel
[Reference] Correspondence table of configuration schemes supported by each family of FPGA
This time, we will focus on active serial (AS) configuration among configuration schemes.
Check with check sheet
Let's organize the current situation with this check sheet in order to investigate the cause when a problem occurs in the AS configuration of the FPGA.
[ Target device family ]
- Stratix® Series: Stratix® V, Stratix® IV
- Arria® Series: Arria® 10, Arria® V, Arria® II
- Cyclone® Series: Cyclone® 10, Cyclone® V, Cyclone® IV
