11 years agoIs there an easy way to establish static reconfiguration of transceivers (VOD etc)
Last time I did an FPGA (Stratix IV) you could set transceiver analog properties (VOD, preemphasis etc.) right in the Megawizard. This was convenient if you did not mind re-compiling each time they w...

11 years agoYou can still assign all transceiver analog properties statically from the Assignment Editor.
Go to "Edit Logic Options" under the "Assignment Constraints" Click on "Assignment Name". It opens a huge drop-down menu. Navigate to "Transmitter..." settings. (attached is the screenshot) Those constraints will be added to project's *.qsf file, for example:
set_instance_assignment -name XCVR_TX_VOD 32 -to xcvr1
set_instance_assignment -name XCVR_TX_PRE_EMP_1ST_POST_TAP 3 -to xcvr1 Those and other transceiver analog settings are described in Quartus QSF reference guide, and you can add them manually without any GUI. Thanks, Evgeni
