Features
added mod_val, enbl_flux_fb_mod, enbl_bias_mod parameters. Once the modulation is enabled, values specified by mod_val are going to be added to flux_fb or bias. This can be used to run an internal ramp on mod_val values and having ramps with different offsets being run on individual bias lines.

Revision 5.2.0 (Stable)

Filename
bc_v05020000_28nov2011.sof
Features
ln_bias lines wake up to 0V and an 'rb bias' command returns the content of the RAM block used to refresh DACs from. This RAM is initilized to 0. Note that Rev. F cards have bipolar DACs and 0V corresponds to 32768 (mid range) as oppose to 0. Therefore, an initial readback from RAM does not return valid values!!! I claim that this is not confusing!
critical_err_rst and fpga_clr commands are supported now. critical_err_rst only works if JP2 jumper inserted.

In non-multiplex mode: flux_fb values are all loaded at the start of the frame. (Previous versions updated DACs row-aligned as oppose to frame-aligned and this had the undesired effect of refreshing some DACs on one row and rest of the DACs on the following row depending on which clock cycle the command was received. This only matters when running internal ramp on bias-card parameters.)
ln_bias lines are only refreshed once and frame-aligned! a bugfix!
Bugs
ln_bias lines are set to code 0 or -5V at power up and need to be cleared to 0V by issuing an exclusive command upon startup.

Revision 5.0.7 (recommended)

Filename
bc_v05000007_22jun2011.sof

Revision 5.0.5 (recommended)

Filename
bc_v05000005_20jul2010.sof
Features
based on 5.0.4, but updated for Rev. F/D hardware pinout.
card_type parameter now includes the pcb-revision information as well as the card_type. card_type is specified as 0x01 as the lower byte (same as before). Reading back card_type parameter returns: 0x0F01 in Rev. D cards, and 0x0601 in Rev. F cards. (Previously, reading back card_type parameter only returned 0x01).
Details
When using tes_bias lines, make sure the count is 12 for bias parameter in mce.cfg file.
When installed on Rev. D file, tes_mapping has to have offset =11 in mce.cfg.

Revision 5.0.4 (lab use)

Filename
bc_v05000004_20may2010.sof
Features
build based on 5.0.3 for Rev. E cards
Biases are refreshed 1 clock cycles after the start of a new row, regardless of whether they are running in multiplex mode or not and whether it is a regular bias line or low-noise bias line.
Details
NOTE If this firmware is loaded on a Rev. D card, it's harmless. The only functionality loss is that the bias command will not work as unfortunately DAC CS and CLK pins are swapped for the bias DAC between the two revisions of the card.

Revision 5.0.3 (Rev. E cards)

Filename
bc_v05000003_12may2010.sof
Features
build based on 5.0.2 for Rev. E cards
added fb_col0 to fb_col31 and enbl_mux commands to accommodate row-based sq2fb switching. When enbl_mux is asserted for a column, then the DAC is refreshed on every row visit with the value specified by fb_col# command.
Details
The original Bias Card design has a buffer after the DAC that is too slow followed by kHz range RC filters, so in order to enable the multiplexing feature, one has to make sure that the BC hardware is modified as per ECO-xxx (to be added here).
card_type returns 5 (indicating a Rev. E)
If this firmware is loaded on a Rev. D card, it's harmless. The only functionality loss is that the bias command will not work as unfortunately DAC CS and CLK pins are swapped for the bias DAC between the two revisions of the card.
combinational loops present in previous versions are removed now
There is 9+16*2=41 clock cycle (820ns) delay for the bias to be applied after the start of a new row. This combined with another 400ns delay due to inherent DAC delay is about 60 clock-cycle delay.
To do
The excessive 41 clock cycle delay to apply a new bias has to be reduced. It is conceivable to preload the DACs and reduce this delay to 1 to 2 clock cycles.

card_type parameter is set to 5 (bias-card Rev. E)
All DACs are loaded at once as oppose to previous revisions that loaded them one after next.
DAC clock is now 25MHz and generated by PLL, previous firmware had 12.5MHz clock generated by dividing down.

If this firmware is loaded on a Rev. D card, it's harmless. The only functionality loss is that the bias command will not work as unfortunately DAC CS and CLK pins are swapped for the bias DAC between the two revisions of the card.
To do
All ln_bias lines are controlled at once and this should be modified to independent control.
Bugs

ln_bias_0 doesn't work, because the data line for ln_bias_0 is not connected in firmware.

Revision 5.0.0

  • Filename: bc_v05000000_22dec2008.sof (tagged as sys_v05000000_22dec2008)
  • To Do:
  • Features:
    • IMPORTANT: Must be used in conjunction with firmware v05000000 of all other cards!!!
    • To allow enough data bandwidth, the spare LVDS line from each card to the Clock Card is now used
  • Details:
  • Bugs:
    • None yet reported
