おかしなエラーで Fitting が終了できませんでした。

Design main has been optimized and fit into device XC95288XL-7-TQ144.

と出た後に、

ERROR:ProjectMgmt:387 - TOE: ITclInterp::ExecuteCmd gave Tcl result 'can't read "iFileType": no such variable'.

とか、明らかにツールのバグっぽいエラーが生じているのですが、 同様の問題に関する ISE 13.4 に関する報告が、

http://forums.xilinx.com/t5/CPLDs/Please-help-with-Nonsense-error-ProjectMgmt-387-TOE-when-running/td-p/230943

にあって、原因も不明のまま放置されているようでした。

どうやら Project Navigator 側のバグっぽいなと感じたため、 cpldfit を直接コマンドラインから実行してみたところ、

LANG:console
$ cpldfit -intstyle ise -p xc95288xl-7-TQ144 -ofmt vhdl -optimize speed -htmlrpt -loc on 
-slew fast -init low -inputs 54 -pterms 50 -unused ground -power std -terminate keeper main.ngd

Segmentation fault

となって、cpldfit が最後に SEGV でコケていることが判明しました。

Project Navigator がこれを正しくハンドリングできていないこと自体もバグですが、 その前に cpldfit が SEGV するバグが主原因ですね。。。

とはいえ、これでは結局理由は分からない。
