# This TCL script is used to do basic project setup and clarify the DRP settings
#
# XAPP888 TCL commands:
#       xapp888_create_project <> - Basic project setup. Adjust as needed
#       xapp888_help <>           - Descriptions of added TCL commands
#
# XAPP888 TCL DRP Settings:
#       xapp888_drp_settings <CLKFBOUT_MULT>  <DIVCLK_DIVIDE> <PHASE> <HIGH|LOW|high|low>
#            - Displays & Returns the ordered pairs of DRP addresses & Data
#
#       xapp888_drp_clkout <DIVIDE>  <Duty Cycle e.g. 0.5> <Phase e.g.11.25> <CLKOUT0 to CLKOUT6>
#            - Displays & Returns the ordered pairs of DRP addresses & Data
#
#       xapp888_merge_drp_clkout <list>
#            - Returns the ordered DRP addresses/data merging fractional address 07 & 13
#
# Revision History:
#       10/22/14 - Added TCL DRP commands
#        3/17/16 - Added min/max duty cycle checks
#        7/10/18 - Fixed duty cycles for divide > 64
#       19 Sep 2018 - Add new lookup tables for CP RES LFHF
#       05 Oct 2018 - Cosmetic updates to text.

    \nXAPP888 TCL commands:\
    \n      xapp888_create_project <> - Basic project setup. Adjust as needed\
    \n      xapp888_help <>           - Descriptions of added TCL commands\
    \n\nXAPP888 TCL DRP Settings:\n   The following TCL commands are being added to give example calculations\
    \n   for drp programming values for MMCME2 (7 series). For other architectures care\
    \n   should be taken due to VCO and programming addresses. This script can be altered\
    \n   to adjust for those differences but exact settings should be reviewed.\
    \n\n   Also please note that this is a subset of the full programming options.\
    \n   Fine phase shifting and dynamic phase shifting is not directly supported by\
    \n   these scripts.\
    \n\n      xapp888_drp_settings <CLKFBOUT_MULT>  <DIVCLK_DIVIDE> <PHASE> <BANDWIDTH>\
    \n           - BANDWIDTH can be: LOW, LOW_SS, HIGH, OPTIMIZED (case insensitive). \
    \n           - Displays & Returns the ordered pairs of DRP addresses & Data
    \n      xapp888_drp_clkout <DIVIDE>  <Duty Cycle e.g. 0.5> <Phase e.g.11.25> <CLKOUT0 to CLKOUT6> \
    \n           - Displays & Returns the ordered pairs of DRP addresses & Data
    \n      xapp888_merge_drp_clkout <list>\
    \n           - Returns the ordered DRP addresses/data merging fractional address 07 & 13
    \n\n   For Example:\
    \n\t   xapp888_drp_settings <m> <d> <phase> <bw>;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout0;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout1;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout2;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout3;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout4;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout5;\
    \n\t   xapp888_drp_clkout <div> <dc> <phase> clkout6;\
    \n\n   To show how to use the xapp888_merg_drp command the following is an arbitrary example"
