In the User Guide for Virtex-II Pro (v2.4), page 287 says that TDO has no internal pullup and that a recommended value of 200 Ohms external pullup should be used on TDO.
However, this pull-up is not shown in Figure 4-5 on pg 290. So, should the pull-ups be used?
Yes. There pull-ups should be shown on the TDO lines in figure 4-5 of the Virtex-II Pro User Guide.
