altera excalibur 시리즈는 APEX 20KE 시리즈를 내장한다고 하니.. qartus 9.0을 써야 할 듯
그런데 최신 버전은 20.1 이라는게 함정 엄청(!) 구석기 시대 꺼구만?
Part of the Altera® Excalibur™ embedded processor solutions: system-on-a-programmable-chip (SOPC) architecture (see Figure 1 on page 4) builds upon features of the APEX™ 20KE family of PLDs, with up to 1,000,000 gates (see Table 1 on page 2)
The AutoCAD web app is supported by 64-bit Google Chrome, 64-bit Mozilla Firefox, and 64-bit new Microsoft Edge (Chromium based) on Windows or Mac.
For the best performance, it is recommended to use the latest version.
Note:AutoCAD isn't currently supported if you are using Firefox with private browsing. Firefox with private browsing prevents the use of service workers, a technology that is needed to internally communicate between the AutoCAD engine and the AutoCAD user interface. If you wish to use private browsing, you can use Google Chrome in Incognito mode.
