Was ist der Unterschied zwischen Port und Analyse-Port? Wo kann man uvm_blocking_put_port verwenden und wo wird uvm_analysis_port verwendet? Was ist der Vorteil von uvm_analysis_port gegenüber uvm_blocking_put_port?Wo können Sie uvm_blocking_put_port und uvm_analysis_port verwenden?
Port-Verbindung wird verwendet, um zwei unabhängige Blöcke (Komponenten) zu verbinden. Sowohl uvm_blocking_put_port als auch uvm_analysis_port werden verwendet, um Daten vom Produzenten zum Verbraucher zu übertragen.
(1) uvm_blocking_put_port: Wird für die Datenübertragung von einem einzelnen Hersteller zu einem einzelnen Verbraucher verwendet.
(2) uvm_analysis_port: Wird für die Datenübertragung von einem einzelnen Hersteller zu einem einzelnen Verbraucher oder mehreren Verbrauchern verwendet.
Vorteil für diesen Analyseport ist, dass ein Benutzer Daten von einem einzelnen Hersteller zu mehreren Konsumenten übertragen kann, die nicht mit Hilfe von uvm_blocking_put_port archiviert werden.
Dieses Ding wird auch in der Abbildung erklärt.
Hier stelle ich Beispielcode zur Verfügung, um mehr Klarheit für uvm_blocking_put_port und uvm_analysis_port zu erhalten.

Denken Sie daran: Port-Verbindung verwendet wird, um zwei oder mehrere unabhängige Komponente zu verbinden.
