What do you use as CORE when cramming Z80 into an FPGA?

Hello, All Actually, subject. I came across an implementation of the Z80 CPU for FPGA in OpenCores. It is stated that up to 300 MHz... Or I didn’t understand what, and we are talking only about MHz please, but there will be no real match to the MHz of the computer. P.S. http://www.opencores.org/projects.cgi/web/wb_z80/overview I didn’t finish reading it, however. The guy got 90MHz, he’s upset... But still a lot.

Hello, Vladimir Kladov 800 MHz is possible on the MAX3064 current passive cooling is desirable, and on the MAX7128 in principle, it’s stable at 200-250 MHz, it’s just that the article is old; it wasn’t like that then elementary base like right now

Hello, Vladimir Kladov Indeed, there is another implementation nearby, a little under another name, but the number 80 in the title should have immediately suggested... There as 250MHz specified, updated in 2006.
