This works transparantly for all programs without any need to modify them. text/html 2009-06-22T11:40:54+02:00 Jaroslav Sykora http://necago.ic.cz/doku.php?id=sc2vhdl&rev=1245663654&do=diff SystemC to VHDL translation tool. sc2vhdl is a software tool for extraction of a model from source texts in the SystemC language, which is used in the industry for simulation of digital circuits. Contrary to other similar programs the structure of a hardware is extracted from the model which has been elaborated. Therefore even models constructed dynamically can be processed. text/html 2009-06-22T11:38:42+02:00 Jaroslav Sykora http://necago.ic.cz/doku.php?id=start&rev=1245663522&do=diff [Avatar] Jaroslav Sýkora e-mail: jaroslav (point) sykora (on) gmail (point) com icq: 253-790-162 (Necago) jabber: necago@jabber.org My Projects icon project name/link sc2vhdl SystemC to VHDL translation tool.

Na straně jedné získal velmi vysoké hodnocení kritiky , na straně druhé jsem se po jeho shlédnutí nemohl ubránit rozpolcenému dojmu, že něco není dobře. Po delším přemýšlení jsem -- doufám -- došel k důvodu svých rozpaků: film má špatný název. A'ST je zřejmě výborný sci-fi film, není to ale Roddenberryho Star Trek, který je nám důvěrně známý. Abrams se tím ovšem netají, neboť A'ST je “reboot”. Myšlenka jakéhosi “rebootu” ale není zase … text/html 2009-06-12T18:00:01+02:00 Jaroslav Sykora http://necago.ic.cz/doku.php?id=tech-bits:latex-float-list&rev=1244822401&do=diff The following LaTeX example demonstrates how to create the “List of Something” page (from custom floats) which is similar to “List of Figures” and “List of Tables”.
