Why are the names of Intel® Stratix® 10 Hard Processor System(HPS) I2C signals for FPGA routing in s10_5v4.pdf different to those shown in Platform designer >Generate>Show Instantiation Template?

Description

Due to a problem in the Intel® Stratix® 10 Hard Processor System Technical Reference Manual s10_5v4.pdf version 2018.08.08, the names of HPS I2C Signals for FPGA Routing are different when compared with Platform designer>Generate>Show Instantiation Template. 

Resolution

The Intel® Stratix® 10 Hard Processor System Technical Reference Manual is due to be updated to change the names of HPS I2C signals for FPGA routing as shown below:

Current Signal Name	Change it to
i2c<#>_scl	i2c<#>_scl_in_clk
i2c<#>_out_clk	i2c<#>_clk_clk
i2c<#>_sda	i2c<#>_sda_i
i2c<#>_out_data	i2c<#>_sda_oe

This problem has been fixed in the 19.4 and latest release of the Intel® Stratix® 10 Hard Processor System Technical Reference Manual.
