Hi,
I'm trying to follow the SDI core on an S4 GX dev kit board. See also: http://www.altera.com/literature/ug/ug_sdi_ii.pdf Altera provide an example design S4GXSDI_AUDIO_TOP In this guide the apply a pin constraint on page A-7set_location_assignment PIN_99 -to sdi_rx
However, the S4 GX has names starting with a letter and then a number. For example : The design has "sdi_rx_p" on PIN_L2. Anybody every encountered this mismatch in user guide versus design. Can I just use the PIN_L2 instead of PIN_99? Rgds, Kimberley

Hi Kimberly,
I rarely use the example designs as the "golden" reference for a kit, I always use the schematic (or at least confirm each pin in the golden reference with the schematic). I've attached my pin constraints file. Here's the SDI section from that file:
# Video out clock control (p6,9 )
set pin(sdi_clk148_up) {PIN = AH12, IOSTD = "2.5 V", DRIVE = 12mA, SLEW = 0}
set pin(sdi_clk148_dn) {PIN = AH11, IOSTD = "2.5 V", DRIVE = 12mA, SLEW = 0}
# Video out control
set pin(sdi_tx_sd_hdN) {PIN = V29, IOSTD = "2.5 V", DRIVE = 12mA, SLEW = 0}
# Video out
set pin(sdi_tx) {PIN = K4, IOSTD = "1.4-V PCML"}
set pin(sdi_tx(n)) {PIN = K3}
# Video in
set pin(sdi_rx) {PIN = L2, IOSTD = "1.4-V PCML"}
set pin(sdi_rx(n)) {PIN = L1}
--- Quote Start --- Can I just use the PIN_L2 instead of PIN_99? --- Quote End --- Yes, pin 99 is wrong, pin L2 is correct. Cheers, Dave
