The
guidelines for transceiver applications that run at ≥ 2.97 Gbps data rate.
The Quartus II software version 10.0 SP1 and prior releases incorrectly allowed logical
channel 0 to be placed in any physical channel for the PCIe Gen1 × 1 interface with the
hard IP block. For correct operation with the hard IP block, logical channel 0 must be
placed in physical channel 0.
This issue is fixed in the Quartus II software version 10.1. If you have already
designed or fabricated your boards using the incorrect mapping, file a service request
using
Using the clock output of another PLL to drive the PLL input of a transceiver is not
allowed. Only the direct REFCLK or DIFFCLK pins driving the PLL input of a transceiver
is allowed.
Hence, PLL cascading for transceiver applications is restricted by the Quartus II
software version 10.1 and later. If you use PLL cascading for transceiver applications,
the Quartus II Analysis and Synthesis reports an error during compilation.
The ±500 PPM and ±1000 PPM options for the Programmable PPM Detector feature in
the ALTGX MegaWizard
supported in the Quartus II software version 10.0 SP1 and later. These options are
removed because the programmed PPM threshold values exceed the receiver CDR
PPM tolerance between the upstream transmitter reference clock and the local
receiver reference clock.
