Overview

Version 1.8.4a of the V6M6 software and FPGA configurations includes the following changes:

• Bug fix for the library functions that control IM2E1 and IM2T1 TDM clock generation logic.

Bug Fix For IM2E1 and IM2T1 Clock Detection Control Functions

The host library functions that control the TDM clock generation mode for IM2E1 and IM2T1 modules had a bug that caused them to not properly set the TDM clock generation mode. The mode in which those modules generate TDM clock at 3.8 PPM faster than the faster of their two incoming derived clocks was not being set.

The host library functions, im2e1_rcvclk, im2t1_rcvclk and pci_tdm_timing in this version are fixed to perform this operation correctly.

Note that the bug still exists in later releases of the V6M6 software, up to and including release 2.0.0. Release 2.0.1 includes versions of these functions with the problem resolved.
