Add SimpleScope firmware for monitoring AMACv2 Output

amacv2_scope_ip package

The core of the new functionality is part of the amacv2_scope_ip package.

It contains the new simplescope entity that monitors an input signal and logs the following:

• number of times the input signal changed (0->1 or 0->1 transition)
• the +/- 16 bits around the last transition detected

The top-level block is the amacv2_scope entity. It institates multiple simplescopes, connects them to all AMAC digital outputs and allows readout via AXI.

The following AXI registers are available:

• 0x00 : reset all scopes by writing to bit 1
• 0x02+2*ch : counter from scope at channel ch
• 0x02+2*ch+1 : last trace from channel ch, frozen with transition at center

The following signals are monitored at the given channel (ch):

• 0 : LDx0en
• 1 : LDy0en
• 2 : LDx1en
• 3 : LDy1en
• 4 : LDx2en
• 5 : LDy2en
• 6 : HrstBx
• 7 : HrstBy
• 8 : LAM
• 9 : GPO
• 10 : DCDCadj
• 11 : DCDCEn
• 12 : Ofout
• 13 : RO_PG_O

firmware integration

An instance of the amacv2_scope_ip package is added to the top-level block under the name axi_amacv2_scope_0. It is connected to the address range starting at 0x41C30000. It can be readout using UIO in the PetaLinux project.

Warning: The UIO devices files in the PetaLinux project are now reshuffled. This means that the mappings in software have to be updated. The new map is:

• /dev/uio0 : amacv2_digital_io
• /dev/uio1 : amacv2_scope
• /dev/uio2 : endeavour
• /dev/uio3 : freqmeas
