5.  C6657 Lite EVM FPGA Functional Description 

 

This chapter describes the FPGA functionality of C6657 Lite EVM board. It contains: 
 

5.1 

FPGA overview 

5.2 

FPGA signals description 

5.3 

Sequence of operation 

5.4 

Reset definition 

5.5

5.1 FPGA Overview 

 

The  FPGA  (Xilinx  XC3S200AN)  controls  EVM  power  sequencing,  reset  mechanism,  DSP  boot  mode 
configuration  and  clock  initialization.  It  also  provides  the  transformation  of  TDM  Frame  Synchronization  signal 
and Reference Clock between AMC connector and DSP. 
 
The  FPGA  also  supports  4  user  LEDs  and  1  user  switch  through  control  registers.  All  FPGA  registers  are 
accessible by TMS320C6657 DSP. 
 
The key features of C6657 Lite EVM EVM FPGA are: 

 

C6657 Lite EVM Power Sequence Control 

 

C6657 Lite EVM Reset Mechanism Control 

 

C6657 Lite EVM Clock Generator Initialization and Control 

 

TMS320C6657 DSP SPI Interface for Accessing FPGA Configurable Registers 

 

Provides Shadow Registers for TMS320C6657 DSP to Access Clock Generator Configurations Registers 

 

Provides Shadow Registers for TMS320C6657 DSP to Access UCD9222 Devices via PM Bus (RFU) 

 

Provides TMS320C6657 DSP Boot Mode Configuration switch settings to DSP 

 

MMC Reset Events Initiation Interface 

 

Provides transformation of TDM Frame Synchronization and Reference Clock between AMC and DSP 

 

Provide Ethernet PHY Interrupt (RFU) and Reset Control Interface 

 

Provides support for Reset Buttons, User Switches and Debug LEDs 

 

5.2  FPGA signals description 

 
This  section  provides  a  detailed  description  of  each  signal.  The  signals  are  arranged  in  functional  groups 
according  to  their  associated  interface.  Throughout  this  manual,  a  „#‟  or  „Z‟  will  be  used  at  the  end  of  a  signal 
name to indicate that the active or asserted state occurs when the signal is at a low voltage level. 
 
The following notations are used to describe the signal and type.
